Sir Alex Ferguson didn't make too many wrong decisions during his 27-years in charge of Manchester United but one he's currently regretting is, of course, his handling of Paul Pogba.
The Scot allowed the Frenchman to leave in 2012 for a compensation fee of £800,000. Now, United are set to 125 times that amount to bring him back to Old Trafford.
Confirmation of the £100 million deal is imminent. So, after four years in which Pogba and United have enjoyed contrasting degrees of success, the 23-year-old is reunited with the Red Devils.

Ferguson allowed the midfielder to leave after he made just seven first-team appearances. We can only speculate the position United would be in now if the then-United boss had gifted Pogba more opportunities - and not picked Fabio to play in midfield over him in a game in 2011, an incident the player was "disgusted" by.
As mentioned at the top of the article, Ferguson rarely made a wrong step at United. As such, United supporters came to agree with his every decision.

So when he let Pogba walk out of the door, they didn't fret. In fact, some joined in when Ferguson slammed the France international for showing a perceived lack of respect.
We've rounded up the best tweets from United supporters reacting to the news of Pogba's departure. Needless to say, there are plenty who will be trawling through their Twitter feeds and clicking that delete button.
Ferguson brought in Nick Powell from Crewe Alexandra one month before Pogba's departure, giving United fans yet more reason not to fear Pogba's exit. Powell was a young prospect and cost £6 million; there was no way Ferguson would spend that much on an 18-year-old for him to be a flop.
Like Wayne Rooney before him, Powell would lead United to glory for the next decade. Or so fans hoped.
Four years later and Powell finds himself at Championship outfit Wigan Athletic.
Some got it right
We've got to give credit to those supporters who realised four years ago that United would regret letting Pogba walk.
Jose Mourinho will make the former Le Havre man his fourth signing of the summer, following the arrivals of Eric Bailly, Henrikh Mkhitaryan and Zlatan Ibrahimovic.
There is huge pressure on the United boss to make this work. Or else he, like Ferguson, will be ruing the decision he made on Pogba.
