Jose Bosingwa's agent has dismissed rumours the Porto right-back has agreed terms with Manchester United.
The 25-year-old Portugal international has been linked with a move to Old Trafford in the English press, but Rui Neno insists nothing has been agreed.
'There is not any sort of agreement with Manchester United,' he told PA Sport.
Neno claims no club has yet matched Porto's valuation of the player but reckons Bosingwa could be interested in a move.
'If any club bid the 30 million euros 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 in some quarters as a possible long-term successor to Gary Neville, who has endured an injury-plagued campaign.
But the Red Devils would have competition if they were planning to make a bid, according to Neno.
'What has happened is that clubs from, Spain, Italy, England and recently Germany have shown interest in the player,' added Neno.
'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 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 of the interested parties.
'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.'
Neno added that Bosingwa - a regular in Luiz Felipe Scolari's Portugal squad for Euro 2008 qualifying - was ready for the next challenge in his career.
'What does he say? Well, he is receptive to offers and says that this is a good season to move on.'
