Arsenal boss Arsene Wenger believes Everton are lacking confidence.
The Gunners enjoyed a routine victory yesterday.
"They are a good side," said Wenger.
"They are a very good team but that shows you that in this league the difference between teams is very small and that even against a team of that quality, once you don't win you lose a bit of confidence and you lose games. They are a very good team and they play good football."
