Even if Van Gaal does decide to keep Rooney in the middle of the park and play two other forwards up top, there are better options out there than Falcao.
Edinson Cavani is one name that has been mentioned and the forward is dying for a move to the Premier League.
Add to that the likes of Mauro Icardi, Gonzalo Higuain and Karim Benzema all looking for potential summer moves and you can see why United are reluctant to commit to Falcao permanently.
