How Costa Rica could line up against Spain

A 4-3-3 formation should become a 4-5-1 when not in possession of the ball, with veteran goalkeeper Keylor Navas set to feature between the sticks.

At the back, Carlos Martinez and Bryan Oviedo should operate in the full-back areas, with Francisco Calvo and Oscar Duarte in the middle.

Sunderland teenager Jewison Bennette will feature in central midfield, and he should be joined by Yeltsin Tejeda and Gerson Torres.

Celso Borges is the most experienced player in the squad in terms of caps, featuring on 155 occasions for his country, and the 34-year-old is set to play off the right for Costa Rica.

The bulk of the players in the national team's squad are midfielders, with limited options when it comes to the centre-forward spot, but Anthony Contreras should get the nod over Johan Venegas.

Contreras has scored twice in nine appearances for Costa Rica, and he is likely to play in the middle of a front three, while Joel Campbell is a certain starter.

The 30-year-old, formerly of Arsenal, has scored 25 goals for Los Ticos, and he is expected to be an important player for his side at the tournament.

Costa Rica possible starting lineup: Navas; C Martinez, Calvo, Duarte, Oviedo; Tejeda, Bennette, G Torres; Borges, Contreras, Campbell
