Along with Juan Jose Rodriguez, Vallejos was one of two surprise selections in Alexander Guimares' squad.

Impressed for the Costa Rican youth team last year and was drafted into the full squad for their two-game tour of Japan and Korea recently.

He, like Rodriguez, is likely to be a fringe player at the World Cup - but will look to shine if handed a chance.
