Questions for the second half
How will Uruguay change things up?
Perhaps bringing on Gaston Ramirez to get things flowing in midfield would help La Celeste create more chances. So far, Cavani and Forlan have looked isolated up top.
How many can Colombia get?
You get the feeling that if Colombia go 2-0 up, the floodgates will open and this could get embarrassing. Rodriguez and Jackson Martinez are giving Uruguay the runaround.
