Arsenal defender Oleksandr Zinchenko commented on his poor performances in some matches for the London club.
"I am the footballer who will evaluate myself. For this there is a coaching staff and a mentor who will evaluate my game. I know I make mistakes every day on and off the pitch, but I'm learning from it. But the most important thing is to realise that we are all human and we make mistakes. Yes, there are times when I make mistakes and sometimes I lose concentration. It is important to solve these problems and try to avoid them in the future," Zinchenko is quoted by Arsenal's official website.
