A historic win for 10 man Costa Rica.
Navas played an absolute gem today and saved a penalty from Gekas to allow Umana to score and seal Los Ticos place in the last 8.
Not a great game as the match only had fits and spurts of action!
Duarte will miss the clash against the Netherlands after being dismissed midway through the second half.
Greece, who scored in injury time for the second successive match, were unable to take advantage of the extra man as Mitroglou and Gekas wasted chance after chance.
