The goalkeeper will retire after the Europa League final against Chelsea, where he could return as sports director.
Emery said, "I don't know, but I know he plays the drums! He is a special man. I want to play with him one day! I said that to him months ago. I said that to him, and it is amazing!
"One day in the Europa League we were in BATE Borisov and they were asking him in Russian and I said, you understand Russian? He said yes coach! It was amazing! He can speak a lot of languages. I worked in Moscow and even I don't know Russian!"
