Aaron Ramsey says he becomes a different person as soon as he steps on the pitch as an Arsenal player.
The Welsh midfielder, who is an easy-going person in general life, compares his state-of-mind on the pitch to the flicking of a switch.
"It's pretty much like flicking a switch in my head," Ramsey told Arsenal Player.
"I give everything when I'm on the pitch or on the training pitch. When I'm at the training ground and working in the gym or whatever, I always give everything that I've got.
"As soon as you feel as though you have a responsibility in the team, you're confident, you want to be out there expressing yourself and I'm in that place. In this team I feel comfortable enough to feel as though I can play my best football. I'm really happy on the pitch at the moment."
