Arsenal goalkeeper Emiliano Martinez is delighted with his form.
Martinez has kept two clean sheets in two victories since taking over from the injured Wojciech Szczesny.
He said: "If you can keep a clean sheet in training at Arsenal you are the best goalkeeper in the world!
"I have a tough time in training with the likes of Danny (Welbeck), (Alexis) Sanchez and Olivier Giroud.
"You are struggling to keep a clean sheet in training at Arsenal let me tell you, but I'm glad to have them on our side for matches when we go out there."
