GREENOCK actor Martin Compston has had a 'fan boy' moment after meeting a UFC legend.

The Line of Duty star, who is best known for playing Detective Sergeant Steve Arnott in the hit BBC show, posed up with Randy Couture.

The pint-sized Scot showed off some of Randy's top UFC prizes in the snap which he shared on social media.

He is also pictured with Scots actor pal Gianni Capaldi.

Martin, 33, said: "Not quite collection my mother has from my Morton under 12s player of the year season but still pretty impressive.

ā€œAbsolute legend and total gentleman. Randy Couture knows his way round a Moscow mule top man.ā€

Couture became a three-time UFC Heavyweight Champion, two-time UFC Light Heavyweight Champion, an interim UFC Light Heavyweight Champion and the UFC 13 Heavyweight Tournament winner.

Although now retired from the sport, he is the first of only four fighters to hold two UFC championship titles in two different divisions
