Nani has promised Sir Alex Ferguson he will deliver if he is handed a starting spot at Wembley on Saturday.
With Antonio Valencia impressing since his return from a broken ankle and Nani's performances dipping slightly, it has seemed increasingly likely the 24-year-old will miss out on a place in Ferguson's team when they square up to Barcelona in the Champions League final.
But the Portugal winger said: "I have played against Argentina and Spain and always done well. Barcelona's football is the same and the players are the same. I like to play against teams who play that way. It is good for me. I feel happy because I know when I play against those players, it will go right."
Yet Nani also views Barcelona's star names as the men who set a standard he needs to match.
For so long overshadowed at United by the vast contribution of Portugal team-mate Cristiano Ronaldo, Nani has blossomed since the former world player of the year's departure to Real Madrid two years ago.
He is adamant further development is possible though, and watching Lionel Messi at home on TV only fuels his desire to get better.
"When I am at home and watching TV I think about Barcelona's players in a totally different way than if I am playing against them," he said.
"At home, I appreciate the way they play. Messi is the best player in the world. I like to see him play and see the things he does. He inspires other players to do different things as well.
"But on the pitch I want to be better than them. Every day I am on the training ground I always practice. I want to improve the things I am not good at. I am trying to be mentally stronger.
"I am not perfect but feel with more experience I can contribute more to the team."
