Nani is yet to decide what the summer will hold for him, but insists there is no guarantee that he will leave Manchester United.

The Portugal international is about to enter the final year of his contract at Old Trafford and no extension has been put in place.

It has been suggested that United would be willing to sanction a sale when the transfer window re-opens, while Nani is said to be open to the idea of taking on a new challenge.

He is, however, keeping his cards close to his chest when it comes to speculation regarding his future.

Nani has been linked with a number of clubs in the Premier League and across Europe, but he has refused to rule out the prospect of remaining at United.

He said: "My future? Nothing is certain.

"I am calm. I have everything in my hands.

"I am not saying that I will not continue at Manchester United. I will think about what is best for me."
