"When I came here I knew about the problem with my ankle. I was seen by doctors and the doctor here has highlighted exactly the problem I have and said it can be fixed. He has a very good picture of the injury," he said.
"I am here for the long term and I'm hopeful the problem will be cured for good.
"Obviously I want to get playing as soon as possible and I don't think that will be a problem. Obviously it's a different type of league to Italy but I don't think that will be a problem either.
"I think the Premier League is the most difficult. It's one of the best leagues and there are some very important teams here. It's a very difficult level but I'm very excited to be playing here.
"We're definitely one of the candidates to win the Premier League.
"It's a shame I can't play straight away but I am putting my all into getting better and I can't wait."
