Apparently we signed him as no one wanted him..
Falcao's father reveals striker turned down moves to City, Arsenal and Liverpool - Manchester Evening News
Hmm but City were limited by FFP restrictions. Juventus and Serie A simply don't have that much of a pull. Arsenal were late to the party as usual. I suspect Liverpool didn't show much of a concrete interest as they already have Baloltelli and Sturridge and the owners wouldn't have sanctioned Falcao's wages
Interestingly, in the same interview if I am not wrong, Falcao's father mentions how he was all set to go to Real Madrid before they inexplicably pulled the plug. So definitely a bit of good fortune as well
