Tennis champion Andy Murray has opened up about his Football Manager addiction.
The two-time Wimbledon champion has had his focus firmly on his work on the court from a very young age but he was prone to a fair bit of FM.
But as FM fans will be well aware of, there is no such thing as a casual FM player and soon Murray became fixed on it - constantly obsessing over what changes he was going to make to his Mansfield Town side.
It culminated in a whole lot of late nights for Scotsman, who was nowhere near as fresh as he needed to be for training the next
"I played a lot of Football Manager growing up - it killed a lot of time on the road - but it also became a bit of an issue when I was staying up late to play it," Murray revealed in an interview with BBC Sport.
"I had to cut back a few years ago. When I was in Spain, myself and a friend would have two teams each - we were staying up until 3am, and we would start training at 8am, so I had to stop playing it.
"As far as football coaching goes, I have been asked if there were any other jobs I would be interested in doing, and I would like to do something in sport.
"Football is something that has always interested me and, it would be a fun thing to try.
"A lot of people think they could do a good job, and that they know what teams should be doing, but there is a lot more to it than that."
Murray might be a self-confessed FM addict but he's still a long way behind Sepp Hedel from Germany. He set the Guinness World Record for the longest ever Football Manager game when he completed 333 seasons and racked up an insane 1,940 hours of actual playing time without simulation or in-game vacations.
He managed FC United, Bengaluru FC and Hereford FC across 333 seasons, playing 15,768 games and winning 11,217 to give him a 71% win ratio.
