Ronald de Boer says Louis van Gaal will not be happy with Manchester United's playing style.
Van Gaal has been criticised for United's possession game.
But former Ajax star De Boer told talkSPORT: "Van Gaal is struggling a little bit at Manchester United.
"Not with the amount of points he's got, but with his style. It's not the way he wants to play. He's fighting to get there.
"At the moment it's not the football that we are used to with Louis."
