Jose Bosingwa's agent has dismissed rumours the Porto defender has agreed terms with Manchester United. The 25-year-old Portugal international has been linked with a move to Old Trafford, but Rui Neno insists nothing has been agreed.

"There is not any sort of agreement with Manchester United," he said.

Neno claims no club has yet matched Porto's valuation of the player but insists Bosingwa could still be interested in a move.

"If any club bid the €30 million (£24m) set by the club, I believe there might be agreement," he said. "In Bosingwa's contract there is not any buyout clause preventing him from negotiating."

Bosingwa is seen by some as a long-term successor to Gary Neville, who has endured an injury-plagued campaign, however according to Neno, United face stiff competition to sign the player.

"What has happened is that clubs from, Spain, Italy, England and recently Germany have shown interest in the player," Neno added. Given his style of play, I really think that he would adapt easily to the Premier League, despite the fact some other European clubs have shown their interest."

Neno also confirmed he has had contact with some English sides, but insists Aston Villa are not among them.

"Yes, but I prefer to keep quiet as it would be unpleasant to name those clubs' names now," he said. "I just have to say that Aston Villa are not among those clubs. I have no idea where these suggestions [of Villa interest] came from. I have never been contacted by anyone from Aston Villa. It does not seem to me that the player would be interested to sign for Aston Villa, with all respect to the club. He would match up to a Champions League side."
