Bern Leno insists there is a good atmosphere in the Arsenal dressing room ahead of the 2019/20 season.
Unai Emery has injected a number of young players in the squad this summer, with new signings Dani Ceballos and Gabriel Martinelli also featuring in friendlies.
Speaking after Sunday's 2-1 loss to Lyon, the Gunners goalkeeper said: "I think the atmosphere in the team is very good. It was last year also very good.
"When you see how the experienced players help the young players adapt, it's very good. And you see on the pitch everybody is like a big family, but we can also talk about negative things.
"Nobody gets mad at each other. I think it's also important to be honest with each other. That's what you need for a good performance and for a good team."
