World Cup 2018 continues today as day 4 sees three matches take place including Costa Rica v Serbia in Group E
The match comes from the Samara Arena in Russia, and will be shown live on ITV
The Costa Ricans were the surprise package of the tournament four years ago in Brazil.
They surpassed expectations by topping a strong group containing Uruguay, Italy and England, before eliminating Greece in the last 16 and eventually falling to the Netherlands on penalties in the quarter-finals.
However, they will see getting off to a good start here as imperative to their chances of repeating their heroics, with matches against Brazil and Switzerland to follow.
The Serbians are also unlikely to be pushovers, as they finished top of a qualifying group ahead of the likes of Republic of Ireland, Wales and Austria.
They will be looking to make amends for their disappointing showing when they last reached the finals eight years ago and failed to progress beyond the group stage.
Match commentary comes from Joe Speight and Iain Dowie.
