"It was probably our best performance of the season": Jose Mourinho's post-Everton reaction
United kept pace with their city rivals at the top of the Premier League table.
On the game
"I think the performance was very good, especially int 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.
"We brought some consistency to the game and then I felt we could go with the counter, with Martial for the last minutes for a result that was too much, too heavy for them, they don't deserve to go with this result."
On United's formation
"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 were 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."
"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."
On Martial taking the penalty
"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."
On Valencia's goal
"An amazing goal, but I think the performance was good even in the difficult moments. The team was consistent, solid, showed solidarity. I am really pleased. I think 4-0 is too heavy for them, too heavy for the effort they brought to the game."
