Manchester United midfielder Ander Herrera insists they can be happy to have overcome Everton yesterday.

United were criticised for their performance in the 4-0 win.

"It was really tough, Everton are a great team," said midfielder Herrera, whose introduction as a 77th-minute substitute gave United fresh impetus for those crucial final stages.

"We should have been winning by at least two goals but you know when you play against Everton you are going to suffer. That is what happened.

"In the second half they had a couple of chances but the best keeper in the world (David de Gea) was there for us. After that we killed the game in the last minutes."
