#3 Paul Pogba's absence
It does not need a footballing genius to tell you that United will dearly miss Paul Pogba this weekend. Manchester United are a better side with the Frenchman, and they play a lot more freely when he is around.
The Red Devils were sitting on top of the Premier League table before Pogba's injury and fell behind city by 8 points during his absence. Even the performances of Romelu Lukaku shows a distinct dip when Pogba is not around. United are completely a different side without Pogba, looking flat and unable to break opponents.
