Jose Mourinho: Our best performance of the season

United scored within five minutes against Everton as Antonio Valencia fired a fantastic volley past Jordan Pickford.

They only added the other three goals in the final ten minutes but Moruinho was happy with his team’s performance.

"I think the performance was very good, especially in the first 30-35 minute, it was probably our best performance of the season.

"We pressed them and they did not have a chance to get out, they did not have a shot, it was very impressive. After that, Everton's good players came out and showed their qualities. They gave us difficulty but I looked behind me on the bench and saw alternatives.

"The Premier League now is becoming very trendy with five at the back, so the best way to play against that is to play five at the back yourself. When you try not to match the tactical system of the opponent, you take risks. So we played with three up top plus Henrikh Mkhitaryan. You have to kill the game and give them little chances. There was a moment where I felt we did not kill it so we have to make it solid with Ander Herrera. The second goal went in, then game over."

Mourinho made it clear that he felt that Everton, who have lost their last three games 3-0, 3-0 and 4-0, would be fine and they are just having a tough period fixtures-wise.

"They did not have much but had a couple of chances. I remembered Swansea last season with Gylfi Sigurdsson, they scored through a free-kick towards the last minutes and it ended 1-1.

"Everton are going to be fine but they are living a difficult moment. The fixtures they have got, I would not like this all together at the same time. I would like one of the top five, but all of them, that is not fair for them.”

Everton have already faced Manchester City, Chelsea and United away from home as well as Tottenham Hotspur at Goodison Park.

Mourinho also said he had no issue with Anthony Martial taking the penalty to score the fourth.

"The penalty-taker today was Juan Mata, but he was out so I let the players take the decision. It is nice for Anthony Marital, fine for me, no problem."
