But he concedes that they will have to avoid results such as Saturday's 2-1 defeat at previously-winless Reading if they are to contend for a UEFA Champions League place.

"There is a lot of quality in the team, and a lot of ambition, and I hope at the end of the season, Everton will finish in the top four.

"We need to win games like that if we want to finish in the top four. We will start again on Saturday. Getting three points is the most important thing."
