Hercules Gomez made the point that if you're going to play someone like Ferreira up top, you don't want someone like Gressel always crossing the ball in against bigger CBs like Canada has. You'd want Vasquez out there.
I wouldn't mind a Cowell Vasquez Ferreira front 3. Cowell can break down the left on the dribble, Vasquez there for the crosses, and Ferreira crosses well (was even taking corners and free kicks in the second half).
