Manchester United have dismissed speculation over Radamel Falcao's age after a newspaper revived rumours that he is two years older than he has claimed.

Falcao's stated age is 28, but The Sun said it had uncovered documents that showed the Colombia international's birthdate to be Feb. 10, 1984 -- which would make him 30.

The striker, who has moved to United on an initial one-year loan from Monaco, dismissed similar claims as "ridiculous" last summer, and the Daily Mail reported that the Old Trafford club were satisfied there was no issue when assessing his documentation before the transfer.

A United spokesperson told the paper: "We were aware of the rumours, but it was never an issue for us."

The Mail added that United's primary concern in completing the deal was ensuring that the player had fully recovered after rupturing the anterior cruciate ligament in his left knee in January.

Falcao, who featured for Colombia as a substitute in their 1-0 friendly defeat to Brazil on Friday, said afterwards he felt he was now in "spectacular" condition, adding: "I have been able to play without any kind of trouble whatever."
