De Boer signed a three-year deal, saying his priority was to make Palace a "solid Premier League club" after its recent battles to avoid relegation from England's lucrative top division.
It's done. Frank de Boer is the new head coach of Crystal Palace and will be, all being well, for the next three years.
The Dutch coach added that his new role is "a hugely exciting opportunity" and he is looking forward to starting work with the Premier League side.
De Boer's short spell at Inter was his second stint as manager with his first being a hugely successful five-and-a-half years with Ajax where he won four successive Dutch titles.
De Boer has been out of work since leaving Inter Milan under a cloud back in November of a year ago.
'Also for the fans, we must try to be attractive.
It was exclusively revealed by The Sun that Crystal Palace chairman Steve Parish had offered De Boer the hot seat at Selhurst Park.
The 112-times capped De Boer said he had been in touch with Louis van Gaal and got a lot of encouragement from his compatriot.
"That's where I want this club to be".
Dutchman de Boer was told where his priorities lay by chairman Steve Parish who pointed out that Eagles home form was the reason they are always fighting to for their salvation. Sometimes you have to play a little bit more reactive football, but I want to play dominant if we can, and if not, we have to be very compact. "We will look at one or two signings, but I think it is necessary to see all the players here first".
Ajax defender Joel Veltman, 25, could be a possible target for de Boer in his efforts to strengthen defensively.
"It is an interesting league to see what you are capable of, fitting a team (together) that is good enough for the Premier League".
