I didn't understand why Palace took him in the first place. They knew the players they already got were so attached to the kick & rush playing style by Alan Pardew and later on Sam Allardyce.
But Palace are a joke of a club (their "Italian-Ultra" like fans are a laughing stock LOL) and very, very poorly run IMO. You cannot bring a new manager in and sack him after 4 games. That Steve Parish guy is a fool. Okay, they played very poorly and De Boer made many mistakes and should've switched to an Allardyce like 4-4-2 after their second loss, but sacking him after 4 games is pathetic. Allardyce didn't win for 5 games last year in december.
And most dumb decision of all would be if they took Roy Hodgson as his replacement. Only good thing Roy ever did was that 4-1 win over Rubentus with Fulham.
