Louis van Gaal has revealed he apologised after mocking Alexis Sanchez with a theatrical dive in the dug-out during Manchester United’s 3-2 win over Arsenal.

The Dutchman sent Old Trafford into hysterics with his impression of Sanchez 76 minutes into Sunday’s Premier League clash by strolling up to the fourth official, uttering a few words and hurling himself to the ground, notebook and pen still in hand.

Speaking afterwards to Sky Sports, Van Gaal admitted he had gone too far and revealed he had offered his apologies to the officials concerned.

He said: “That was too emotional – it is not good for the authority of the referee and the linesman and the fourth official.

“It doesn’t happen much normally – I have had a lot of criticism because I am sitting on my bench and now I am off my bench and I have lot of criticism because I’m doing that.

“I have apologised to the referee and the linesman and they have accepted it. I hope everything is solved. I have to control my emotions and I have said that also to my players.”

Wenger refused to criticise Van Gaal after the match when asked what was his opinion on his opposite number’s touchline antics.

“Nothing,” Wenger replied. “You will have to ask him the question. I do not want to comment on that because [you will say] I’m a bitter loser – I am, in fact.”

In other Manchester United news, Wenger has claimed Van Gaal can build his team around teenage striker Marcus Rashford, who has scored a remarkable four goals in the first two matches of his senior career.
