United and City £40m Argentine Target: "Anything can happen in football..."

Edinson Cavani has continued to play the line that he is happy at Napoli, but the Manchester United and City striker target has admitted that a move is always a possibility in the future.

Cavani has been one of a group of breakthrough stars for Napoli, with the side overcoming big-spending City in the Champions League to reach the final 16 stage and look one of the biggest threats besides Real Madrid and Barcelona.

And while United and City have both been monitoring the Argentina international very closely, he insists that he is perfectly happy in the Serie A, though a move next summer could be a possibility.

"In Naples, I'm fine," Cavani told Sky Sport Italia. "The people give me lots of love and I hope that always continues to be the case. In the future, though, you never know [and] this is football."

United are suffering from a great deal of injuries at the club, and while Javier Hernandez and Dimitar Berbatov are getting back to full match fitness, Michael Owen is still recovering. With Cavani a highly coveted player across Europe, Sir Alex Ferguson may choose to bring the striker on board to create more competition for places up front.

United will also be keeping an eye on how far City are willing to go to lock Cavani down, after the club's chief scout admitted he was chasing the star, along with his teammates Marek Hamsik and Ezequiel Lavezzi.

The cross-town rivals may have been watching closely as reports surfaced of an altercation between Cavani and Napoli manager Walter Mazzarri recently, but he insists that the problem was solved and the pair have moved on.

"I had a little spat with the coach but we have already solved the problem," Cavani said. "It was a deserved victory [against Genoa] and now we can go on holiday peacefully."

Napoli stole the march on Premier League giants Chelsea to snare the signature of Chile international Eduardo Vargas, and while the club is still waiting to confirm his move to the club, £30 million-rated Cavani says he can't wait to play alongside the forward.

We know he's a great player, we're waiting for him," he explained. "We hope he fits well in this team but I do not think there will be any problems because this is a great group."
