Gilks has joined up with the Scotland squad ahead of a friendly against England on Wednesday night, while Cathcart is set to feature in Northern Ireland's rearranged World Cup Qualifier against Russia. 

On-loan Liverpool man Jack Robinson has also reported for international duty, with the left-back part of an England Under-21 squad to face their Scotland counterparts on Tuesday. One absentee, however, is Thomas Ince who has pulled out of the squad due to a groin problem.
