#2 Eric Bailly
Eric Bailly arrived at Old Trafford as Jose Mourinho's first signing as the United boss in 2016. From his first appearance in the league, he has shaped up to be the player the club had been craving for in defence.
He cost the Red Devils's £30 million but was an investment one shouldn't have regretted.
The Ivorian is known for his strength, pace, tackling and bravery in front of the forwards. Bailly is exceptional when it comes to throwing himself to challenges and making interceptions.
The 23-year-old has often been hailed to be the successor of Nemanja Vidic at the club and has justified his credentials so far. He has made only 16 appearances in all competitions this season.
Injuries have hindered his consistency and progress which could see him as one of the best defenders not only in England but in Europe.
