Manchester United forward Robin van Persie has rubbished rumours suggesting that he requires knee surgery.

Reports claimed that the Dutchman is set for a long lay-off and hence, Louis van Gaal went on to sign AS Monaco striker Radamel Falcao on a season-long loan.

However, the former Arsenal striker, who struggled with fitness problems last season, has denied the claims and confirmed that he is fully fit.

"I don't know where these rumours are coming from," van Persie said, as quoted on Goal.

"I can honestly say that I will not visit a hospital any time soon to undergo surgery. You need quite a lively fantasy to come up with this nonsense," the Dutchman fumed.

The Holland striker also went on to praise Falcao and believes that all the strikers now have to fight for their place in the team, including the new signing. He also welcomed the competition for places and arrival of top quality players, as he feels it will only improve the club further.

"I am happy with the arrival of Falcao," the Dutchman continued.

"He makes us a better team. You always have to aim for the best at a big club. That's my philosophy as well. Falcao has to fight for his place, just like me. The two of us and Wayne Rooney and James Wilson will have to fight it out," the former Arsenal skipper explained.

The Colombian international striker was one of the most sought after players during the last day of the transfer deadline day, with multiple clubs trying to land him including Arsenal, Manchester City and Real Madrid.

However, the former Atletico Madrid striker chose Old Trafford ahead of the other clubs and will now remain on-loan for the season, with an option of making it permanent the following summer.
