Costa Rica have taken everyone by surprise at this summer's World Cup and need to beat Greece in the Round of 16 to reach their first ever quarter-final.

As one of the least well-known nations in Brazil, we wanted to get to know them a little better.

We were joined by Matthew Levin, ESPN's Costa Rican football expert who profiled the team and also gave us an idea of the fever which has gripped the small Central American nation, including Sloth Kong!

He also made one key point about this generation of Costa Rican players which includes the likes of Keylor Navas, Joel Campbell and Bryan Ruiz.

"This is the first time there has been a huge emphasis on a team from outside Costa Rica," said Levin, citing the aforementioned players.

"The team really relies on a lot of people from outside the country."
