It hasn't been plain sailing for Paul Pogba since he rejoined Manchester United and now we might know what the problem has been.

There have been a handful of examples in recent soccer history where Manchester United has not seen the talent that they have in front of them, or at least don't know how to nurture and get the best from it. It happened with Gerard Pique, who has since gone on to Barcelona and become one of the best defenders in the world, and also with Paul Pogba when he made the move to Juventus from United in 2012.

The extremely talented Frenchman has since returned to Old Trafford, however, it cost the Red Devils a pretty penny. During the summer of 2016, when United re-signed Pogba, it set them back a staggering $120 million, a record transfer fee at the time. Many United fans would argue that Pogba is yet to live up to that hefty price tag, and he may have recently revealed one of the reasons why.

As reported by Sky Sports, Pogba recently opened up about some of the issues he has had with Manchester United boss, Jose Mourinho. "It was an experience. There were some small issues with [Mourinho], but they were nothing in the end", the 25-year-old admitted. It certainly sounds as if he is telling the truth too as his second season back in Manchester proved to be far better than his first.

It may still seem to some that Pogba is underperforming because of how much he cost, but his stats for last season tell an interesting story. The French international may have only netted six goals for the reds, but he managed more assists than anyone else in the team and the fourth highest amount of anyone in the Premier League during the 2017/18 season. He will need to improve on that if United want to challenge Manchester City in the title race next season though.

His life at United will likely be at the back of Pogba's mind right now. That's because he is currently in Russia representing France at the 2018 World Cup. His side takes on Denmark on Tuesday this week and will be able to relax a little. That's because they have already qualified for the next round and will just be focusing on trying to finish first in Group C. If they do finish top, Argentina could very well be lying in wait in round two.
