When he arrived at Old Trafford, many fans thought that Nani could achieve great things at Manchester United, following in the footsteps of the Cristiano Ronaldo, by becoming a huge success in England.
But this season has seen a big decline in form of the Portuguese winger, with rumours circulating once again about a possible move away from Manchester for speedy midfielder.
A good campaign last year for United, left many of their fans hoping that this was the season that he truly came of age and showed his full potential. But so far, this has failed to happen.
There is no doubt that he has the qualities and attributes that could lead to him becoming a great player, but as of yet, he has failed to reach the levels that Sir Alex and United fans would have expected at this stage in his career.
And facing stiff competition in the side with the likes of Antonio Valencia and Ashley Young, Nani must prove himself if he hopes to remain at Old Trafford, with just a few months of the Premier League season remaining.
Despite links with moves over the years, Fergie has continued to keep faith in Nani, but now it is time for him to repay this faith and start to show his worth as United look to win their 20th league title.
His omission from the squad that faced Real Madrid in midweek, was a slight surprise with the pace he has, but having played poorly when given his chance this season, he cannot expect to be included in such a match
Now it seems he is fighting for his Old Trafford future, and although there is no doubting his natural ability, if he is to stay at Manchester United, he must convince Sir Alex he has what it takes.
Failure to deliver now, will count more than ever as United seek to claim back the Premier League, as well as continue in the Champions League and FA Cup.
