Real madrid, not a chance considering aguero saga.
Barcelona ? bullshit. Messi forced zlatan out of the center because he wanted to be playing there. There is no way Falcao would push messi to the right flank again.
City ? looking at the fuckload of forwards they got, not sure. If he comes, dzeko will leave.
Chelsea ? can they afford him again ? can the russian pay another massive price ? not sure.
P$G ? zlatan-falcao, would be fapworthy, the best strikerduo in the world. however it would also mean they spend more then 50 mil on young strikers they are now shelving. since they are a team without a vision, perhaps this would work.
