Arsenal goalkeeper David Ospina doesn't rate himself the new first-choice ahead of Wojciech Szczesny.
Ospina was impressive in victory over Everton on Sunday.
He said: "Here you are fighting in every training session. Arsenal has some great goalkeepers and that's what's important.
"The manager takes the decision, but every one does their own job, the competition is healthy and I hope to continue making the most of the opportunity I've been given.
"This competition pushes you to be better, always. At the level we're at, in a team like Arsenal, you always have to keep performing to stay in the team and this helps you to work much harder and to improve every day."
