"No one knows him here but I am sure you won't have to wait long to get to know him. He proved in France he could play for a big team and I am sure [he will prove himself] here after a few months Â because you always need a few months to adapt to the English football.
"I hope he does well for the team, the Club and for himself because he is a good guy, he is a friend of mine. I hope he will show everyone that he deserves to be in one of the biggest clubs in the world and can play here for many years."
