Everton manager Marco Silva said: "It was a difficult match like we expected.
"We had a better first half and we created better chances, but we showed a lack of focus in the goal we conceded. We reacted well and had clear chances which could have changed the match.
"We knew what they came here to do which was to wait for our mistake. I think the stats suggest we controlled the match. To break their organisation you have to play faster and we didn't do that in the second half. We take it game by game and our mentality is to win and do what we can."
