After qualifying against all odds in their respective groups, Costa Rica and Greece meet in the Round of 16.
Costa Rica finished top of a group containing three former champions as they beat Uruguay and Italy and drew with England to secure top spot in Group D.
While Greece managed a 2-1 victory over Ivory Coast in their final game to reach the Round of 16 for the first time in their history.
Costa Rica have been arguably one of the most impressive sides in the competition with Bryan Ruiz and Joel Campbell both producing top performances in their three games.
Their opener against Uruguay was a solid performance as they beat the 2010 Semi-Finalists Uruguay 3-1. Their second game against Italy was more of a battle hardened display as they managed to scrap a 1-0 win over the Azzuri in Recife.
Costa Rica may have been more impressive than Greece in the Group Stages but manager Jorge Luis Pinto is rejecting the notion that Los Ticos are favourites: “I don’t know if we want to be favourites. We don’t feel like favourites. We’ll give it our all.
“Our results have given us confidence and stability, they demonstrate what we’re worth.
“We’re well prepared physically and we’ll give our all, with the same respect that we confronted the three world champions.”
Greece have been contrasting to Costa Rica, far from exciting, they've been the solid unit we've come accustomed to over the last ten years. They may have lost their opener 3-0 to Colombia but a 0-0 draw with Japan and a 2-1 win over Ivory Coast saw them scrape into the knockout rounds as they did at Euro 2012.
The Greeks have only scored two goals in the tournament so far and one was a penalty. That would be enough to worry any coach but not Fernando Santos: "We showed against Ivory Coast how well we can defend but also how good we can be in attack."
"We created a lot of chances and we kept attacking until the end. Even when we conceded the 74th minute equaliser, we continued to attack."
