United face Liverpool at Old Trafford on Sunday and Nani has already won more titles than Gerrard.
Nani told The Sun: “I do not know about the intentions of Steven Gerrard this summer but it is normal that a player with his quality desires to win titles and if this doesn’t happen in Liverpool he could think about leaving.”
Nani is confident ahead of their clash with Liverpool.
He said: “I bet we do not lose one match at Old Trafford until the end of season.”
He said: “In the summer I included Liverpool in the group who would race for the title and I am surprised at their situation. Perhaps injuries to key men have damaged them.
“It won’t be easy for them to finish fourth. The other clubs will put up a terrific fight and the slightest change can affect the whole situation.
“It’s a bit like our own battle to be champions.”
Nani added: “I have been in England for three years and I’ve seen the enormous rivalry between United and Liverpool. It’s not just a game for three points – the pride of the fans is at stake.
“So this is a very special match for me which we must win to maintain our morale for the remaining league matches.”
