#2 Paul Pogba (Juventus vs Manchester United)
Paul Pogba's famous fall out with the legendary Sir Alex Ferguson is common knowledge for football fans. Manchester United lost the Frenchman on a free transfer to Juventus in 2012.
Pogba left no stone unturned in proving how wrong United were in cashing in on him. An instant hit with the Bianconeri fans, he played a crucial role in Juve's road to the finals in the UCL 2015.
The same competition has now put Paul Pogba on a tough emotional test: facing the club where he grew up to be the man.
With the Red Devils already under pressure after losing two of their opening three games in the league, they will be under increased pressure to perform in one of the toughest groups of the competition.
When Mourinho and co visit his former rivals in Turin, Pogba will shoulder a mammoth pressure to deliver given his intermittent performances and the prospect of facing the club that transformed him into a top-notch footballer.
