Manchester United's Nani is confident his side can get a positive result against FC Porto in the Champions League on Wednesday night.

The Red Devils are behind on away goals going into the second leg of the quarter-final in Portugal knowing that no English team have defeated Porto at their home ground.

"Why am I confident? Simple, because we have the best players in the world," Nani told The Sun.

"We have the confidence wherever we go. OK, we know Porto are a very good team, play good football and showed their own strengths at Old Trafford.

"But it may be more difficult for them now. When you're at home you have to go forward more, and that could leave them under pressure.

"We are going there to win and we're confident we can do it."
