Anfield humiliation has shattered Arsenal's confidence, claims Wenger.
Arsene Wenger believes Arsenal have lost their danger factor since February's defeat to Liverpool.
Everton compounded the Gunners to a 3-0 defeat at Goodison Park earlier today as Roberto Martinez's side continue to fight the north Londoners for the final Champions League qualification spot.
And Wenger feels that their hammering at the hands of Premier League title challengers Liverpool three months ago has had a psychological impact on his side in their top four pursuit.
When asked in his post match press conference whether their 6-1 reversal at Anfield had affected his players, he replied: "Yes, until then, we were very strong away from home.
"We had the best record in the league away from home so psychologically we've lost a big confidence - and today as well, we went behind early.
"Everton were very good on counter attacks, but I still feel we had a lot of the ball but we're not really dangerous."
He added: "It's very difficult to identify if it's fear. I would just say that maybe our big defeats away from home have taken something of our charisma away from the team. Is that [a lack of] fear, belief or confidence? Maybe a bit altogether.
