Hazard struggled to make an impact for Belgium in Brazil.
Wenger said: "No, he did not play as well as I know he could and in the Premier League he is an exceptional player and he is a fantastic player who makes things happen and I always had the idea that with Eden Hazard nothing affects him. In the big games he is great but in this tournament when Belgium really needed him he could not really deliver and I believe it’s mental.
"He is still young and the World Cup belongs to people between 25 and 30, you know, and we have seen Messi before going to World Cups and being anonymous. And whilst he was dominant for his club, he struggled for Argentina. So there is a huge pressure that is put on players in the World Cup and only the really experienced players can handle that."
