#2 He is an extremely divisive figure
In his three years at Old Trafford, Paul Pogba has managed to cause disunity at the club which has affected the playing atmosphere.
His excessive social media presence has been a constant source of problems; while he also had an infamous fallout with former manager Jose Mourinho with things reaching a point where the 26-year-old lost his starting place before his manager's dismissal in December 2018.
His animosity with the Portuguese reportedly divided the dressing room, with some players being on his side while others were on the side of their manager.
Paul Pogba is a very influential player who has a lot of clout and as such wields a lot of influence in any dressing room he finds himself in, but this could work against Real Madrid in the long run.
The dressing room at the Bernabeu is one of the biggest in the world, with some of the greatest players in history. These players also have very inflated egos and Pogba's arrival could potentially unbalance the hierarchy which would not be beneficial to the club's rebuilding plans.
