#4 Klaas-Jan Huntelaar - £24.3 million to Real Madrid
The only Dutch footballer on the list who did not start his youth career in Ajax, Klaas-Jan Huntelaar made his first steps into the world of football at the academy of arch-rivals PSV Eindhoven.
Huntelaar moved to Heerenveen, following limited playing time at PSV before joining Ajax for the first time in his career in 2006. In his first spell at the club, Huntelaar made 136 appearances and scored 105 times for Ajax and won three major titles with the club. The striker then joined Real Madrid in 2008 after three years with the Dutch giants.
Huntelaar returned to Ajax last summer after spells with Real Madrid, AC Milan and Schalke. The striker in his second stint helped Ajax win the KNVB Cup as well as the Eredivisie, after a gap of four years.
Huntelaar, in total made 211 appearances for the Dutch side and scored 141 goals.
#3 Arkadiusz Milik - £28.80 million to Napoli
Unlike the rest of the names in the list, Arkadiusz Milik was a Bayern Leverkusen reject who came back to the forefront of football after reviving his career at Ajax.
Milik started his football career in Poland with Gornik Zabre before joining Bayern Leverkusen, FC Augsburg (loan) and finally Ajax in 2014, initially on loan before making his move permanent the next season.
Milik endured a tough start to his career before turning his fortunes after his impressive loan spell at the Johan Cruyff Arena. The Polish international stay at the Dutch capital was short but he scored an impressive 47 goals in 75 appearances for Ajax.
