Having failed so spectacularly at Manchester United, Falcao's looking for a fresh start and another chance. Meanwhile, Monaco are looking to offload him (again), thanks to his enormous contract. This is where Chelsea come in, apparently. Just a few days after the player's desperate plea, the Blues are apparently willing to explore this option.
Radamel Falcao's future could be still in England and in Premier League. [...] Josè Mourinho, Chelsea's manager, appreciates his qualities. Falcao is a concrete Blues target for the next transfer market window and the parties have already started to talk.

Falcao's sizable contract with Monaco would require some fancy financial maneuvering to make this whole deal palatable, though our transfer brain-trust did manage to sort out the whole Fernando Torres situation eventually, so perhaps we're better equipped than most to deal with such conundrums. Whether the fans are equipped to deal with another potential Fernando Torres situation is an entirely different question.
