Frank de Boer was the manager of Crystal Palace at the beginning of the 2017/18 Premier League season.
The former defender had an illustrious playing career with Ajax and Barcelona, winning six league titles, the UEFA Champions League, UEFA Cup and UEFA Super Cup between 1988 and 1999.
De Boer left Barcelona in 2003 to join Galatasaray before moves to Rangers and Qatar.
Racking up over 300 appearances for Ajax, De Boer re-joined the Eredivisie club in 2007 as part of their youth coaching set up.
The Dutchman represented his country over 100 times and during the 2010 World Cup, De Boer was the assistant manager of the Netherlands national team.
In December 2010, De Boer was appointed caretaker manager of Ajax before his permanent appointment led to four consecutive Eredivisie titles, starting in the 2010/11 season.
De Boer left the Amsterdam club in May 2016, but was back in management for the start of the 2016/17 season after taking charge of Internazionale in Italy.
However, the Italian side and De Boer went their separate ways in November 2016.
Crystal Palace announced De Boer as Sam Allardyce's replacement in June 2017, but he lasted four Premier League fixtures - the shortest reign in the competition for matches.
