He admits he doesn't enjoy the comparisons with the Real Madrid star.
Nani told The Sun: "I am always in contact with Cristiano.
"He has been a great help to me since I came to the club, along with the manager and Carlos Queiroz.
"But I don't like the comparisons with Cristiano as a player.
"We are different and have attributes to our game that aren't similar.
"But, unfortunately, the public frequently compare us.
"What I can tell you, though, is Cristiano is still a huge United fan and is desperate to see us retain the title."
