David Ospina is enjoying the battle for the No 1 shirt at Arsenal and believes his rivalry with Petr Cech has helped him scale new heights in goal.
The Colombian is set to return between the sticks when the Gunners host PSG in the Champions League on Wednesday night.
Arsene Wenger has made the 28-year-old his preferred choice in cup competitions and Europe this season.
Ospina excelled himself when he started away in Paris during the 1-1 draw in September, and insists that he is relishing the rivalry.
