Martin Compston was visited by a Line of Duty co-star as he trained for the UNICEF Soccer Aid charity match, which will take place this coming Sunday at London Stadium.
Vicky McClure, who starred alongside Compston in the hit BBC drama, was on hand to put the Scottish actor to the test as he trained for the match.
Compston posted an Instagram story of himself and McClure embracing, with the caption: "The auld enemy. @vicky.mcclure", alongside a Scotland and England flag emoji.
