Emiliano Martinez believes Wojciech Szczesny and Lukasz Fabianski were "disrespectful" in their comments about former Arsenal goalkeeper coach Gerry Peyton.
The former Gunners shot-stoppers were not complimentary of Peyton's coaching when questioned in an interview last year.
Martinez told Goal: "I think that was really disrespectful what they said about Gerry. I don't agree with what they said about him.
"When I read that, it was a massive shock. For me, I have massive respect for Gerry. He made some really good keepers at the top level and had been at Arsenal for so many years.
"I improved so much with him. Obviously, Javi [Garcia] is there now, a bit more of a modern coach who wants to play out from the back.
"But in terms of Gerry's positioning and handling, he was one of the best. So, for me, what they said was very disrespectful."
