#3 Paul Pogba
Paul Pogba returned to United as the costliest players in world football a year ago. Pogba was good last season and an ever-present figure in United's midfield with 5 goals and 4 assists in 30 appearances. He did his hamstring in a Champions League game against CSKA Moscow late September. Mourinho confirmed that Pogba is out until at least November and may need a surgery.
What will United miss in Pogba's absence?
He started this season brilliantly with 2 goals and 2 assist in just 4 games. It's not just his goals and assists that United need. Pogba is invaluable to United with his ability to convert defence into attack and his injury is a major setback for United.
In 4 games for United this season, Pogba has made 309 passes, 10 accurate long balls, 10 crosses and 100% tackle success. United's strength in midfield is good but Pogba certainly will be missed.
