Charlton have had their work permit application for Costa Rica winger Christian Bolanos rejected by the Home Office.

The Addicks agreed a one-year loan deal with South American club Deportivo Saprissa for the 22-year-old earlier this month, subject to international clearance.

Despite Bolanos having represented his country 18 times, twice in the World Cup finals, as a substitute against hosts Germany and then starting versus Poland, the player did not meet the required quota of 'A' appearances set down by the Government for non-European nationals.
