Falcao has earned himself a reputation as one of the deadliest strikers in Europe after impressing with Porto, Atletico Madrid and now Monaco, who he signed for last summer in a shock £50m switch - despite many of the biggest clubs on the continent looking to sign him.
His spell in Ligue 1 had been going well, but in January he fell awkwardly, tearing his anterior cruciate ligament - an injury which cane take over six months to recover from. At the time, doctors were optimistic about Falcao making his comeback in Brazil this summer, with the striker's rehabilitation progressing positively.
However, speculation has been rife for days over whether Falcao will be able to take his place in Jose Pekerman's Colombia side at the World Cup, despite being named in their preliminary squad earlier this week. With reports emerging that Falcao will be confirmed as an absentee this week, the striker admitted that even if he does make it, he won't be 100% fit.
"To arrive 100 percent match-fit will be impossible because I am lacking competitive action," he said. "To sum up, if it feels good, I will go. If I see that I am not secure and I cannot bring anything, I will be sensible and not go."
Concerns are beginning to grow over Falcao's availability with the World Cup now just 25 days away, and the striker's father even says that he is only 60% recovered from his injury sustained at the start of the year.
"We must wait and see what happens," he said. "The doctors, who know about these things, say that clinically to begin to play it takes six or seven months. Doing the math he will not have enough time. He is now recovered about 60 percent but still needs force, pace, resistance - a combination of things that are fundamental in a high-performance athlete."
Falcao has long been linked with a move to Chelsea as Blues boss Jose Mourinho looks to improve his striking options, and with a £60m summer swoop suggested, Mourinho would surely have wanted to see how the striker would perform at the World Cup after such a big injury - but it doesn't look like he will get that opportunity, so will he think twice about the bid now
