Nani has lavished praise on Manchester United boss David Moyes.
The Red Devils winger has revealed he is happy playing under the former Everton manager and has lauded Moyes for boosting his confidence.
Moyes' Manchester United reign did not get off to the best of starts as the Red Devils lost three of their opening six Premier League games.
However they have since gone on a nine-match unbeaten run, with the Premier League champions latest win coming against Arsenal just before the international break.
Portuguese international Nani - who has made just four starts in the league so far this season - is happy plying his trade under Moyes.
"The manager has been fantastic with me," said Nani.
"He has been giving me advice and trying to help give me confidence.
"The coaches are trying to get my confidence higher to show all the qualities I have got. They are trying to get me back to my best level."
Nani believes teams are no longer scared of playing Manchester United at Old Trafford - but has tipped his side to return to their best in the next few months.
He added: "It looks like teams are more confident when they come here to play against us.
"But I'm sure we will change that because, at the moment, we are playing without all our confidence.
"I think once results start coming we will show who the real Manchester United are and will do much better."
Nani, who is likely to be involved in Portugal's second leg World Cup qualifier against Sweden, will be hoping he is involved in Manchester United's match against Cardiff City on Sunday.
