Arsenal boss Arsene Wenger says a fully fit Mesut Ozil must fight for his starting place.
Ozil made his comeback in victory over Stoke three months after suffering a knee injury.
Asked if it would be difficult for Ozil to get back in to the starting team, especially with the form of Santi Cazorla as well as Alexis Sanchez, Wenger said: "It is not easy for him because Santi is playing very well.
"It's a fight to get back to his best level."
