Costa Rica have caused one of the surprises of the World Cup by topping a group that included Uruguay, Italy and England.
However, Jorge Luis Pinto's side are fully deserving of a place in the last 16, and they will fancy their chances against a Greece side that only qualified for the second round in the final minute of their match with Ivory Coast.
Greece looked down and out against Ivory Coast on Tuesday evening before Georgios Samaras struck from the penalty spot in added-on time to help his team reach the knockout stages for the first time in their history.
However, the win came at a price as goalkeeper Orestis Karnezis and midfielder Panagiotis Kone both picked up injuries during the game, which leaves them as huge doubts for the showdown in Recife.
