Arsenal manager Arsene Wenger has insisted that he is pleased with the response from goalkeeper Wojciech Szczesny since he was dropped from the side.
Lukasz Fabianski was preferred in goal for the matches against Bayern Munich and Swansea City, which led to Szczesny's father slamming Wenger's decision.
However, Wenger has said that his number one has shown professionalism and determination to get back into the XI.
"I haven't spoken to him [about his father's comments] and I believe he responded very well," Wenger told the club's official website.
"There is a not a lot more to say. We are in a competitive world, he has nearly played 100 games for this club and at his age that is absolutely fantastic. The rest, we have ups and downs in our form and we have to fight against that. That's what he said, basically.
"He has a great future. He is a very young goalkeeper. You do not find very many goalkeepers at his age who have the experience he has already. That's why I believe he has a great future. He lives in a world where competition exists."
The goalkeeper quickly apologised for his father's comments.
