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.

The pair may be friendly in real life, but when Scotland and England face each other, they appear to be bitter enemies.
Earlier this week, Glasgow Live reported that the Greenock-born actor sparked season seven rumours for Line of Duty after posting a snap of the cast together.
Compston hinted that a new season of the hit BBC cop drama could be on the horizon after he tweeted a picture of himself, Adrian Dunbar, Vicky McClure and writer Jed Mercurio.

he posted the pic along with the caption: "Talking tattoo designs".
The caption could be a nod to the agreement he and his fellow co-stars made to get AC-12 tattoos if the show ever reached 12 million viewers - which it did after the season finale was watched by 12.8 million people.
On the tweet, one fan replied: "New LOD script under the menus?"
A second wrote: "Mother of god, you’d better be talking new series plots/plot twists while you’re there!!!"
And a third said: "Definitely a new LOD being discussed. My bet the storyline will be about corrupt cops working for a corrupt government."
Martin will be in the line-up for Soccer Aid's World XI, commencing on Sunday June 12.
