Manchester United's Portuguese winger Nani believes that he has the ability to become one of the best players in the world, having recently been linked with a move away from Old Trafford.
The 23-year-old joined the Red Devils in the summer of 2007, but has taken time to establish himself as a first-team regular.
However, he has been in top form in recent weeks after being linked with interest from Italian club Fiorentina and several clubs in his homeland.
Nani told the Manchester Evening News:"I never wanted to go.
"When you are feeling low and things aren't going well, you do feel alone and there have been times like that. But I never thought about quitting and going back to Portugal.
"I was in a bad position sometimes and it wasn't easy to get back up again. Of course, your confidence does suffer on occasions and you get down.
"But I have shown I don't get depressed too easily, I am a strong personality. If you are not a strong character then it will drag you down.
"I am not like that. I am sure I have the quality to be one of the best in the world. I can achieve that."
