Dirk Jan Klaas Huntelaar (born 12 August 1983), known professionally as Klaas-Jan Huntelaar (), is a Dutch former professional footballer who played as a striker.

Huntelaar played for PSV, De Graafschap, AGOVV Apeldoorn, Heerenveen, Ajax, Real Madrid and AC Milan, before joining Schalke 04 in August 2010, for whom he was the top goalscorer in the 2011–12 Bundesliga with 29 league goals. Huntelaar is also Schalke's second highest goalscorer of all time, behind Klaus Fischer.

Huntelaar was named Dutch Football Talent of the Year and Ajax "Player of the Year" in 2006, and was a part of the Dutch side that won the 2006 UEFA U-21 Championship where he became the tournament's leading goalscorer and received the player of the tournament award. He was also named as one of two strikers in the UEFA Team of the Tournament. He is the all-time top scorer of the Netherlands U-21 national team with 18 goals in 23 appearances.

Early life Huntelaar was born in Voor-Drempt, a village in the Achterhoek region of Netherlands, but moved to Hummelo when he was six weeks old. He lived with parents Dirk-Jan and Maud Huntelaar, and his two brothers Niek and Jelle. At the age of five, Huntelaar, along with his two brothers, joined the local football team VV H. en K., where he played for the next six years. He was scouted as a youth talent during this period by Go Ahead Eagles but the distance required to travel to the team's base in Deventer prevented him from joining the club.

Soon after, he was scouted by De Graafschap and on 6 April 1994 he signed his first youth contract, aged 10. During his first two years with De Graafschap, Huntelaar played in various positions including left wing, attacking midfield, left back, and even goalkeeper; only in his third year was he deployed as a striker.

In the 1997–98 season, the 14-year-old Huntelaar was the main striker for the C-team at De Graafschap and scored 33 goals in 20 matches. The following season saw him promoted to the B1 team, and in the 1999–2000 season he became top scorer of the B1 league with 31 goals. His goalscoring abilities drew the attention of PSV Eindhoven, who subsequently signed him in June 2000.

Club career

PSV In his first season at PSV, Huntelaar quickly established himself as a prolific goalscorer for their A1 youth teams under coach Willy van der Kuijlen, scoring 26 goals in 23 games to become top scorer in the youth league. In his second season at PSV, Huntelaar was added to the senior squad under coach Guus Hiddink. He made his first team debut on 23 November 2002 in a 0–3 away win over Roosendaal, coming on as a second-half substitute for Mateja Kežman in the 76th minute. However, this turned out to be his only appearance for PSV.

De Graafschap By the start of 2003, it was clear that Huntelaar's path into the first team was blocked, therefore he was sent out on loan to his previous club De Graafschap, where his uncle was financial director. He made his senior debut for De Graafschap on 8 February 2003, coming on as a substitute for Hans van de Haar against Roosendaal. He made his only appearance in the starting lineup on 16 February 2003 as De Graafschap were beaten 1–5 by his future club Heerenveen. He then made his final appearance in the team on 29 May 2003 as De Graafschap lost 2–1 to FC Zwolle, confirming their demotion from the Eredivisie. In total, Huntelaar made nine Eredivisie appearances for De Graafschap, one as a starter and eight as a substitute, but was unable to score and De Graafschap decided not to extend his loan.

AGOVV At the start of the 2003–04 season, Huntelaar was again sent out on loan, this time to newly promoted Eerste Divisie side AGOVV Apeldoorn under coach Jurrie Koolhof. He made a solid start, scoring on his debut for AGOVV against TOP Oss, and then scoring a hat-trick in his second league game against Heracles Almelo. Huntelaar scored 26 goals in 35 league appearances and finished the season as the division's top goalscorer as well as being named the Eerste Divisie's Player of the Season. AGOVV later went on to name one of the stands at their Sportpark Berg & Bos stadium the "Klaas-Jan Huntelaar stand" in tribute to his impact at the club.

Heerenveen

At the end of his loan at AGOVV, Huntelaar turned down the opportunity to sign a new contract with PSV, and Frisian club Heerenveen moved in to sign him. Huntelaar started the 2004–05 season by scoring on his Eredivisie debut with Heerenveen against AZ Alkmaar and took his scoring tally to ten goals in 17 games at the winter break. At the end of the season, Huntelaar had scored a total of 17 goals in 31 matches, helping Heerenveen qualify for the 2005–06 UEFA Cup. In the 2005–06 season, Huntelaar continued where he had left off in his first season at Heerenveen, and by the winter, he had scored 17 goals in 15 matches at which point the top Dutch clubs began vying for his signature.

Ajax

2005–06 season In January 2006, Huntelaar signed for Ajax, the club he had supported as a child. Heerenveen received €9 million plus future incentives for the player, with 15% (€1.35 million) of the fee going to PSV. Huntelaar made his Ajax debut after the winter break and scored his first goal for the team on 5 February 2006 against former club Heerenveen in a KNVB Cup tie. In February, Huntelaar scored nine goals in seven matches for Ajax, including against Serie A club Inter Milan on his UEFA Champions League debut. Huntelaar ended the season as top scorer for Ajax with 16 league goals in 16 appearances despite only joining in January, and also finished up as the Eredivise's top scorer with 33 league goals. He scored a total of 44 goals in 47 appearances in all club competitions. Ajax finished fourth in the Eredivisie and Huntelaar featured in the Eredivisie Playoffs for Champions League qualification, scoring in consecutive matches against Feyenoord as well as playing in the victory over Groningen to secure Ajax's place in the following season's Champions League. In the KNVB Cup semi-final, Huntelaar scored a bicycle kick equalizer in injury-time against Roda JC, taking the game to extra-time. Ajax went on to win 4–1 with Huntelaar scoring another goal in the 109th minute. In the final, against his former club PSV, Huntelaar scored two goals to help Ajax win the KNVB Cup 2–1. Huntelaar was named Dutch Football Talent of the Year and Ajax Player of the Year for 2005–06.

2006–07 season

In July 2006, Huntelaar became the first player to score at Arsenal's new Emirates Stadium in a testimonial match for Dennis Bergkamp. He was named vice-captain of Ajax for 2006–07 in his first full season at the club. Huntelaar scored two goals for Ajax in a Champions League qualifying match against Copenhagen to secure a 1–2 away win in the first leg, but a 0–2 home defeat in the second leg saw them knocked out of the Champions League on aggregate. Ajax went on to play in the UEFA Cup, where Huntelaar scored seven goals in seven matches, including against Werder Bremen, who would eliminate them in the third round. In the Eredivisie, Huntelaar scored 21 goals as Ajax again finished second, once more having to play in the Eredivisie Playoffs to claim a place in the Champions League. Huntelaar scored two goals in the second leg of the Playoffs semi-final against Heerenveen in a 4–1 aggregate win. Ajax then beat AZ Alkmaar 4–2 on aggregate for a place in the third qualifying round of the Champions League. In the KNVB Cup, Huntelaar scored four goals in six matches, including an equalizer in the final against Alkmaar which ended in a 1–1 draw after extra-time. Huntelaar scored in the penalty shoot-out decider to help Ajax retain the KNVB Cup, winning 8–7 on penalties. Huntelaar scored 36 goals in 51 games in all competitions for Ajax in 2006–07. 2007–09 In 2007–08, Huntelaar partnered up front with new striking-partner Luis Suárez. However, Ajax were again knocked out of the Champions League at the qualifying stage, with Huntelaar missing a penalty in the first leg against Slavia Prague. Ajax were also eliminated from the UEFA Cup by Dinamo Zagreb on away goals, with Huntelaar's two goals not enough to secure Ajax's place in the competition.

In the first Eredivisie match of the season, Huntelaar scored four goals in a 1–8 away victory over newly promoted De Graafschap. Following the retirement of Jaap Stam in October 2007, Huntelaar was made temporary captain, pending the return of experienced midfielder Edgar Davids from injury. On 6 April 2008, Huntelaar scored his 100th goal in the Eredivise with a hat-trick in Ajax's 4–1 win against De Graafschap. In the previous 25 years, only Dennis Bergkamp and Dirk Kuyt had managed that feat before their 25th birthday. Huntelaar finished the season with 33 goals in 34 appearances, becoming top scorer in the Eredivisie and the first Ajax player to score 30 league goals in a season for 21 years, since Marco van Basten in 1986–87. At the start of the 2008–09 season, Marco van Basten was appointed as Ajax coach and named Huntelaar permanent first team captain. Huntelaar scored nine goals in 15 appearances in all competitions before suffering torn ankle ligaments on 9 November 2008 in a league match against Sparta Rotterdam. He would not play again for eight weeks, and this would turn out to be his last game for Ajax.

Real Madrid

At the start of December 2008, Real Madrid reached an agreement with Ajax to sign Huntelaar in the mid-season transfer window in January. Huntelaar joined Real Madrid in January 2009 for an initial fee thought to be worth €20 million, potentially rising to €27 million. Huntelaar made his debut on 4 January on his return from injury in a La Liga home match against Villarreal. He played for 56 minutes and made four further appearances as a substitute, before scoring his first goal for the team on 15 February in a 0–4 away win at Sporting Gijón. Madrid had planned to add both Huntelaar and fellow new signing Lassana Diarra to their 2008–09 Champions League squad, but both players had already featured in the same season's UEFA Cup for previous clubs Ajax and Portsmouth, respectively. UEFA rules would allow only one of the pair to be registered by 1 February and Diarra was selected to play in the competition. Huntelaar went on to score eight goals in 20 appearances (13 starts and seven substitute appearances) in just half a season at Real Madrid.

A.C. Milan On 6 August 2009, Huntelaar transferred to Serie A club A.C. Milan for €17.75 million, signing a four-year contract. On 29 August, Huntelaar made his competitive league debut for Milan coming on as a sub in the 0–4 loss to cross-city rivals Inter Milan in the Derby della Madonnina. After a slow start, Huntelaar scored his first Milan goals on 29 November in a 0–2 away win at Catania, scoring twice after coming on in the 84th minute.

After the match, manager Leonardo stated that he would give Huntelaar more chances. However, he only appeared as a substitute for the next few matches, and because of the great form of teammate Marco Borriello, Huntelaar did not even appear as a substitute very often until Borriello's injury. Huntelaar capitalized on the opportunity by scoring his second brace of the season, helping Milan to a 3–2 defeat of Udinese. When Borriello hit bad form, Huntelaar was expected to play more often, but Leonardo chose to play veteran Filippo Inzaghi instead. On 3 April, Huntelaar started the match against Cagliari and scored from 30 meters out to stretch his goal tally to seven.
