Joel Campbell and Bryan Ruiz are the main stars.
Campbell’s potential was spotted early by Arsenal, but he spent the 2013/14 campaign impressing at Olympiakos.
Ruiz has spent three years at Fulham, but he was loaned out to PSV Eindhoven in January and will be expected to make a permanent move when the transfer window re-opens following the Cottagers’ relegation into the Championship.
While the pair have issues to resolve regarding their futures at club level, international matters are of greater concern at present.
Costa Rica face a tough task among football’s elite in Brazil, having been placed in Group D alongside England, Italy and Uruguay.
They’re definitely huge underdogs and are expected struggle in the first round of play, and unlikely to repeat the feat of 1990, advancing to the next level.
