Football was famously far more important than life or death for Liverpool manager Bill Shankly - but Arsene Wenger took obsession with the beautiful game to a whole new level.
The newly-departed Arsenal boss would watch footage of matches from around the world after he got back from the training ground, and attended Arsenal games at all levels, from academy up.
His all-consuming fixation with football earned him the nickname 'Professor' with the club's fans, but seems to have cost him his marriage to his long-time love.
Wenger split from his wife Annie Brosterhous in 2015 following a five-year marriage.
