Nani admits he's struggling to make an impression at Manchester United.

Nani, 22, currently on international duty with Portugal, has seen his first-team opportunities limited this season, despite the departure of Cristiano Ronaldo, and says his confidence has suffered as a result.

Speaking to a Portuguese newspaper, Nani said: "People expect more from me and it is not easy. I could be doing better, scoring more. But just think, I had a huge game today, but the next one, I'm not even sure that I will play. Such a situation breaks the confidence."
