Nani insists his rapid progress at Manchester United hasn't come as a surprise to him.
"When I arrived my thinking was this: I'm going to work as hard as possible so that when I'm called upon I'll be at my best possible level. At the start it was difficult, because this squad is really strong, but because of some injuries I got my chance early. The truth is I did well and this left me extremely satisfied.
"The Premiership is very different, everything is at the very highest level. I enjoyed my two years at Sporting but to develop I couldn't have chosen better. Here there are no easy games when you know the winner beforehand, as happens with some matches in Portugal. In England every game is a final."
Nani added: "I don't like comparisons, or that they say that Nani is going to be like Cristiano Ronaldo. I think I've got the ability to reach a very high level, but I want to be known as Nani, one of the best players in the world."
