"I was told I would have to wait another year for citizenship and I was prepared to do that until I met Mourinho," he told the Daily Mail. "Chelsea were interested and I went to see Mourinho in a London hotel.
"But from the moment I met Mourinho I wanted to play for him. He knew things about my game even I hadn't been aware of. He started to tell me how to improve my game. Do this, don't do that. 'Have you been following me?" I said. 'Of course I have,' he replied.
"I thought I can get better under this guy. He is an amazing character, and someone who is true to his word. He helped make me the player I am. He made me strong. I am getting better with each season and I am proud of that."
