Radamel Falcao fitness is big news in Colombia. The striker missing the World Cup in Brazil was of course a huge blow. It was supposed to be Falcao's time to shine and before James Rodriguez became the star of Colombia's World Cup campaign, it was Falcao who was the one expected to lead the country forward. He's still the country's most favoured footballer and and his move to Manchester United has gone down very well indeed. In Colombia it had been thought that Falcao was something of a waste at AS Monaco and the player clearly agreed, pushing as hard as he could this summer for a move to a big club.

There's of course been a niggling worry that Falcao could suffer more problems with his knee after his surgery before the World Cup. Therefore, when news came out that he'd be missing the Manchester United and Chelsea match it led to rumours of that being the issue, those were quickly dismissed.

The Colombian media took the bull by the horns and Gol Caracol contacted Manchester United and those close to the player on Sunday and were told it was a calf problem. Falcao received a knock in training and had a badly bruised calf, there was a worry about a muscle problem and Manchester United were set to conduct a scan as soon as swelling had gone down.

Reports in Colombia on Monday evening suggest that's already happened. El Tiempo and Futbol Red say that a source close to Manchester United has said " What Falcao has is a muscle injury, which will mean he has one, or maximum two, weeks of incapacity. Fortunately it's not serious. It's nothing so big."

That would appear to make Falcao a big doubt for the match against Manchester City at the weekend. Manchester United surely wouldn't want to push things if it's a muscle injury, there could be the danger of making things worse.
