The Republic of Ireland will finish the season with a two-game tour in America taking on Portugal and Costa Rica in Philadelphia and New Jersey.

Martin O'Neill's side will face Costa Rica on 6 June at PPL Park in Philadelphia (1am 7 June Irish time) and Portugal four days later on June 10 (12.45am 11 June, Irish time) at Met Life Stadium, New Jersey.

Both games should prove a worthwhile test for O'Neill's side as Portugal and Costa RIca will both use their games with the Irish as preparations for their World Cup campaign in Brazil.

The fixtures complete a summer schedule that starts with the Three International friendly against Turkey in Aviva Stadium on 25 May, followed by a friendly match against Italy on 31 May at Craven Cottage in London, before the two matches Stateside.
