Manchester United boss Louis van Gaal says their lack of title winning experience has hurt their season.

He claimed United's meek title challenge had been down to a lack of winners in his squad.

"The players we are now playing are not used to being champions," he said. "I don't think [Matteo] Darmian is used to it - [David] De Gea was never a champion.

"[Wayne] Rooney, [Michael] Carrick have been champions once, maybe more than once. You have to see the situation where the club is. We have seen that we are in a transition period."
