This Last 16 tie between Costa Rica and Greece is not one that many people had predicted before the tournament kicked off.
Costa Rica have shocked a few people by finishing top of Group D thanks to wins over Uruguay and Italy before ending their campaign with a draw against England.
No disrespect to Costa Rica, but they were expected to struggle in that very tough group but they dug deep and deserve their place in the second round.
Costa Rica always had confidence in their own ability to qualify, but they have admitted that they hadn’t planned to face Greece.
Midfielder Yeltsin Tejeda said: “We were thinking more about Colombia and the Ivory Coast and in the end came the least expected team. Now we have to change the video cassette.
"They are in the World Cup and they beat an excellent team, Ivory Coast. If they are there (in the Round of 16), it is because they were better.”
Greece needed a very, very late penalty from Georgios Samaras on Tuesday to see his country qualify for the last 16 at the expense of opponents Ivory Coast.
That victory over Yaya Toure’s men, coupled with the draw against Japan, saw them qualify in second place five points behind leaders Colombia.
Greece manager Fernando Santos refuses to take Costa Rica lightly as his side looks to qualify for the qaurter-finals for the first time in their history.
Santos said: “I am delighted first of all that we bring joy to the Greek people. We have time to think about the match with Costa Rica. We will go back to our base, think about it and study our opponents.
“We have to pay a lot of attention to this game, they came out top in the 'Group of Death'. As a result we cannot allow ourselves to underestimate them."
Costa Rica v Greece will kick-off at 2100 BST on Sunday, June 29.
