Watching the Confed Cup, I don't care if Forlan is on his last legs and Cavani is the supposed "it" boy. Forlan is vastly outplaying Cavani. I'm not a Cavani fan in general (and I really want Real Madrid to stay away from him), but he's been poor by any estimation.
FWIW, I think Uruguay's main problem is in the midfield. The team doesn't have a crew that can control the game.
As for Donovan, no one has taken his role since he stepped away from the USMNT. Eddie Johnson and Graham Zusi aren't the answers out on the wings.
