The Dutchman has joined the Eagles on a three-year deal as he replaces Sam Allardyce following the former England manager’s decision to walk away at the end of last season.
De Boer becomes the Eagles third manager in 12 months and arrives after being sacked by Inter last year when he won just five our of 14 games in a three-month stint at the San Siro.
That came after a successful period at Ajax, where the former Netherlands and Barcelona midfielder won four titles in six years.
After missing out on number one target Marco Silva who joined Watford from Hull, Palace chief Steve Parish has turned to the Dutchman.
De Boer said: “I have a good feeling about the club and the perspective of managing a team in the Premier League was very exciting. There are almost no weak teams in the league so I am very excited to be manager of this club.”
Parish added: “I suppose this is the worst kept secret in footabal. We are delighted that he has agreed to join us on a three year deal; we are really excited about what we can achieve together at the club.”
Palace took to social media on Monday morning to suggest that an appointment was imminent, as they posted a video of white smoke billowing out of a Caribbean takeaway, echoing the method that the Vatican use to announce that a new Pope has been appointed.
De Boer’s twin brother Ronald spoke of Frank’s new role in an interview on Sky Sports News at the weekend:
“Frank is very excited, of course. It’s the biggest league – everybody knows it, everybody’s watching the Premier League.
“You can do really something if you have the chance, because there is money involved and you can buy players.
“It’s an interesting league to see what you’re capable of as a manager.
“I know they are talking and I think it’s just about little terms with the coaching staff. I don’t see any problem, but of course it’s not for me to say if it’s a done deal or not.”
