Nani is confident Manchester United can win a Premiership and Champions League Double this season.
"I know it will be very difficult to win both trophies," he said. "But I also know it is possible because Manchester United have a great team and a fantastic squad and we play good football.
"There are certain teams you watch on TV and think it will not be that hard against them. But when you actually meet them on the pitch, it is a completely different matter. They all seem to try really hard because they are playing Manchester United."
Nani's mastery of the English language is improving in tandem with his play.
However, he is now having to get used to the long-held British tradition of festive football.
Even if he is not involved against Everton, it is virtually certain Nani will figure in a packed fortnight which also includes trips to Sunderland and West Ham, plus a New Year's Day encounter with Birmingham before the FA Cup match with Aston Villa on January 5.
For a player who is used to putting his feet up and relaxing at this time of year, the sheer volume of matches has come as a major shock.
"It will be a different type of Christmas Day for me that is for sure," he said.
"In Portugal we never play at this time of year. Here we have five games. It is unbelievable, crazy."
