The Spanish No1 told arsenal.com: "As for Fabianski and Mannone, we are working very well together, we have a very good relationship. We are three very nice guys and we try to work every day for ourselves and for the team of course.
"Also [goalkeeping coach] Gerry Peyton is very easy to work with and at the moment I am enjoying training.
"Lukasz and Vito have both improved because they are young and they have room to improve and become great goalkeepers.
"As one of the oldest players in the team I will try to help them and the other young players."
