Paul Pogba should have been one of the greatest footballers of all time: instead, he became the last of a very specific player

Paul Pogba of Juventus, 2015.

Paul Pogba is just 30 years old – yet he likely won't play football again. Certainly not at the top level.

Following a random drugs test in August, the World Cup winner tested positive for elevated levels of testosterone. He has since been banned from the sport for four years, essentially ending his second spell at Juventus, tarnishing his reputation and putting a big full-stop to 'Project Unlock Pogba', an almost-decade-long pursuit of the perfect environment to get the best from this star.
