Both Uruguay and Costa Rica are missing key strikers in the form of the injured pair of Alvario Saborio and Luis Suárez, so we'll get to find out how they do without their talismans here. Uruguay have simply replaced the Liverpool ace with Diego Forlán, who was probably the player of the tournament in the 2010 edition but has since been somewhere between 'out of form' and 'too old to play organised football', while Costa Rica have apparently elected to go with a 3-4-2-1 using Olympiacos man Joel Campbell as their spearhead.
Considering that Uruguay still have Edinson Cavani up top, even without Suarez you'd have to imagine that they'll be just fine.
