Club Brugge coach Alfred Schreuder is leaving to succeed Erik ten Hag as Ajax coach.
The 49-year-old Dutchman has agreed to a two-year contract with the option to extend by an additional year.
Schreuder, who retired from playing in 2009, has managed FC Twente and Hoffenheim. He was also Ten Hag's assistant at Ajax from January 2018 until 2019.
During Schreuder's time under Ten Hag at Ajax, he held the club reach the semi-finals of the Champions League and win a league and cup double.
Therefore, the Ajax chiefs believe Schreuder is the right man to take over from Ten Hag in the summer.
Speaking about the appointment, Ajax chief Edwin van der Sar said: "We know Alfred as a tactically strong coach with good and versatile exercise material.
"These last years he has gained experience as a head coach and as assistant coach at top clubs in various countries and competitions.
"We have a lot of faith that he will give a good continuation to the path we have chosen at Ajax these last years. In both the Eredivisie and the UEFA Champions League."
Ten Hag is leaving Ajax to take charge of Manchester United.
