Radamel Falcao still has a chance of being fit for the World Cup after undergoing successful knee surgery.

The Colombia striker was involved in an ill-fated challenge with centre-back Soner Ertek during Monaco's French Cup clash with Chasselay last week and suffered a cruciate injury.

But the operation on his knee was a success and the 27-year-old's dream of featuring in Brazil could yet happen.

The Portuguese doctor who performed the operation on Saturday said "there's a possibility of him going" to the finals, which start on 12 June.

José Carlos Noronha, at the hospital in Oporto, said "it's not out of the question" and gave Falcao a better than 50% chance of making it to Brazil.
