Manchester United officials have termed as premature press reports that star winger Cristiano Ronaldo will have to undergo surgery on his right ankle.

The reports said the Portugal international had no option but to go under the knife and that he would be out of action for up for six weeks in order to recover.

Manchester United, however, have issued a statement saying that no decision has been taken on how to proceed with the injury.

'Manchester United medical staff met with the medical team from the Portuguese FA and Cristiano Ronaldo in Lisbon today (Wednesday) regarding the ongoing treatment of his injured right ankle,' the club statement said.

'As a result, further specialist advice is being sought and an announcement will be made on any action in due course.'

Ronaldo's future has been the subject of intense speculation in recent weeks, with Real Madrid striving to lure him away from Old Trafford.

United manager Sir Alex Ferguson has become increasingly frustrated by Real's very public courting of Ronaldo, whose Old Trafford contract runs until 2012. And that led United to report the Spanish giants to FIFA although the global governing body have taken no action against Real.

Ronaldo, who scored 42 goals in all competitions for United last season as they won both the English Premier League and Champions League titles, has added to the uncertainty surrounding his future with a series of contradictory statements regarding whether he wants to stay at United or play for Real.
