Arsenal boss, Mikel Arteta, knows he has two great goalkeepers within his first-team squad.
Bernd Leno had a very good season, but Emiliano Martinez also performed excellently when Leno was out injured at the end of last season.
Now Arteta will have to figure out who plays the most often and when. Leno is fully fit and in pre-season training with Martinez.
Asked who would be no.1 to start the season, Arteta told reporters: “I love to have two goalkeepers at the level of Bernd and Emi.
“Last season, when Bernd got injured, if somebody had some doubts about Emi’s character or qualities then he’s shown what he’s able to do and he didn’t do it for one game, he did it for 10 or 11 games in a row.
“I’m delighted to have both of them. But they both know that on the first day of pre-season, you start again and fight for your place and show us who is the one that deserves the chance to start.
“I don’t want to keep them both happy, I want the one that is not playing to be upset.
“But upset and then challenge the next player to make him better, or if not, earn his place to do that. It’s not easy to do that.
“I personally don’t see any different with goalkeepers to full-backs. They know that, I’ve been really clear with them and hopefully they can make each other better and hopefully the team better.”
