Henrikh Mkhitaryan says he was no longer happy at Arsenal.
The midfielder joined Roma on a season-long loan this summer.
He said: "I have to enjoy playing football, no matter the place. In England, I no longer felt happy.
"I got a call from my agent and I wanted to come, because it was a great opportunity for me. I didn't even have a discussion with my agent about money.
"Maybe I was not fitting so well in English football, so I think a change was good."
