"I think this is the right league for me," he said. "I hadn't played since November 22 - my last match in Russia - so I have been training but I don't think I have reached my peak because it takes time. My future, as far as I'm concerned, is in front of me and I will be fulfilling my potential.
"I am hoping to have a good career [at United] but that depends on my game. But the way I am playing, I hope in my period of time in Manchester it will be one of the best of my life.
"There were offers from other teams and the United offer came last-minute but it is an absolute honour. United presented me with something which was absolutely fantastic.
"I can only say thank you because they have all been very helpful, the players and the manager.
"I would now like to prove myself to show what I can do."
"It's a big honour to come to Manchester United. It's a big club in the world. I would like to show what I can do. There were offers from other clubs, United's offer came last minute, but again I say I didn't have a second doubt as it's an absolute honour as it represents something fantastic."
