Arsenal boss Arsene Wenger has challenged new goalkeeper David Ospina to put pressure on current number one Wojciech Szczesny.
The shot-stopper will reportedly sign for the Gunners after their pre-season tour of the United States has concluded, and the French boss believes that Ospina can threaten the Poland international's place.
He told reporters: "You know at the start Szczesny will be the [first choice], then again we'll be down to performances and, if Ospina shows that he is better, he will play."
Ospina made 29 Ligue 1 appearances for Nice last season.
