#2 Influence of Jose Mourinho
It is quite reassuring for a player when the manager reiterates faith in his abilities at every possible opportunity. Jose Mourinho has publicly backed Pogba as the best midfielder in the world, and backed up his words by changing his system to get the best out of the Frenchman.
Even though they fell out eventually, Eden Hazard's insights into Mourinho's contributions towards his success during the 2014-15 season were pretty revealing. Under the Portuguese manager, the Chelsea winger developed the tactical side of his game; getting better at isolating defenders in one-on-one situations and contributing immensely to defending as a unit.
Pogba, therefore, has found himself under Mourinho's guidance at the best possible time; often criticised for a lack of tactical awareness and positional discipline, perhaps no other coach in the world can instil these traits in him better.
The former Real Madrid and Chelsea manager has indicated his willingness to build a team around Pogba, even in the early stages of his Manchester United career, and his presence on the touchline can work wonders for a talented young player.
