Dwight Yorke has launched a blistering attack on Louis van Gaal and labelled Manchester United as painful to watch.

The United legend has been left stunned by the way United have slumped to four consecutive defeats.

He also hit out at the Dutchman’s decision to drop captain Wayne Rooney for the 2—0 defeat at Stoke that leaves his position as manager hanging by a thread.

 Yorke said: “It’s painful watching. They are lacking in confidence, and have no spark whatsoever.

“I have to say, Louis van Gaal was the right man early on, but in the past three weeks results gone against him.

“Look where they are, they find themselves down in sixth, out of the Champions League, and the side has lost to Bournemouth, Norwich and Stoke — the worst run under Louis van Gaal.

“It’s now you look through the team for leadership, fight, that the players have togetherness, and all those things are missing in the ranks.”

Yorke is convinced that Van Gaal picked the wrong match to demote Rooney to the substitute’s bench.

“The timing on Wayne Rooney was wrong,” explained the former striker. “He has had opportunities to leave Wazza out but not done it.

“To leave your captain out in a game like this is a big call. He’s a manger with a lot of experience, but it went against him. That was the wrong move from Van Gaal.

“Leaving out your captain and talisman, although his performances not been the greatest, I just felt went against him and he got it wrong again.”

Yorke believes it is getting almost impossible to see Van Gaal being able to arrest the slump and turn the club’s fortunes around.

And he says some of that is down to the players the manager has allowed to leave the club — and the poor standard of the signings he has made.

Yorke added: “It’s very difficult for him now. He talks about togetherness in that team, players fighting.

“You expect all players expect to give their all and try to get results for the manager and the fans, but it seems difficult for him to get the best out of them.

“Then you look at the bench to see who can bring something or add something when you need it, and they are short in every department.

“Where are the likes of [Javier] Hernandez, [Ole-Gunnar] Solskjaer, off the bench? This squad just seem to lack that.”
