This has to go down as the worst transfer of all time, when you consider the whole story. They lost him for nothing to Juventus, where he went on to win 4 league titles (8 trophies) and be in the Serie A team of the year 3 years running. Then they pay £90m for him and give him £300k a week (another £90m in wages over 6 years) and never once in that time build a team around him or played to his strengths. Now he leaves again on a free.
Pogba is obviously culpable for his performances at Man Utd to an extent, but his performances in a France and Juve shirt is proof that he's a far better player than we've seen at Man Utd.
