Everton boss Marco Silva says they didn't deserve defeat to Sheffield United.
A Yerry Mina own goal and a late Lys Mousset strike condemned Everton to defeat at Goodison Park.
Silva said: "It was a tough game for us. Of course we didn't deserve the result but when you make mistakes like we did this afternoon you don't get what you deserve.
"For the second goal it should have been easy for our defenders to clear the ball. The second half was bad - not good enough. We need to show more and try new things.
"Some individual performances were not at the level we expect, but that's part of the game. The key moment for me was the mistake we made in the first goal."
