Wenger expects England to go through - and to get stronger as the tournament continues.
"I think England at the moment are not at their best but they still should go through," Wenger told Arsenal.com. "They looked inhibited against Algeria and they played against a team that tried to defend very well.
"I don't know if they peaked in qualifying and certainly they need to play with a little bit more freedom. But any team who does well at the World Cup, none of them peaks in the group stage.
"To do well at the World Cup you start and then become stronger and stronger. England started slowly so will they become stronger and stronger? That is the question you need to wonder about and the question they need to answer."
