I don’t know if I’d call it checkered.
Got World Cup runners up as the Dutch assistant manager in 2010 against the best ever Spanish team (and one of the best in the history of football) the world has ever seen and then went on to win the Eredivisie four times with Ajax.
OK fair enough, it was with Ajax but still. You can only beat the opponents you face and win the league that you’re playing in.
He didn’t last long at Inter, possibly for the same reason as at Palace and to be fair Inter seems to have been a bit of a poisoned chalice ever since Mourinho left and took all their success with him. Don’t think too many manages have really impressed at Inter, so I wouldn’t put all that on De Boer. Since 2010-11 they’ve finished 6th, 9th, 5th, 8th, 4th, and 7th.
And now here we are again with Palace who are very trigger happy and where the general consensus seems to be he’s been unfairly treated.
