Long before Liverpool had an 'Egyptian King' in Mohamed Salah, 'King Kev' was football royalty on Merseyside.

But the departure of Kevin Keegan to Hamburg in 1977 saw the coronation of a new icon - Sir Kenny Dalglish. Oscar winning director Asif Kapadia's new documentary on the now 74-year-old is a tale of triumph and tragedy.

It's packed with nostalgia, from the Roy of the Rovers-inspired opening credits, to brilliant archive footage and never-before-seen clips of his playing career and home life. The razor-sharp witted Dalglish, his wife Marina and ex-team-mates Graeme Souness and Alan Hansen, are just some of the voices who narrate the Scottish striker's story.

A Protestant whose dad supported Rangers but who ended up playing for Celtic and marrying a Catholic, his life is as extraordinary as his footballing talent. Much of the film reveals how he shone for Jock Stein's Bhoys and then Bob Paisley's all conquering Liverpool, his smile a mile wide as he scored and created goals for fun.
