#3 Nemanja Matic
The Serbian's importance to this Manchester United team was evident in the fact that Matic had started all but one of Solskjaer's 13 matches prior to the Liverpool game. From a player who looked tired and ineffective under Mourinho to regaining his old stature back under Solskjaer - Matic transformation under the Norwegian has been nothing short of miraculous.
While Solskjaer deserves all the credit for turning the Serbian's season around, Matic has repaid that favour by a brilliant run in the middle of the park. He is the support that allows Ander Herrera and Paul Pogba to flourish and immerse themselves in their duties without worries. He is the stability that provides confidence to the United back four and more often than not, he is also the source of exquisite balls from the back that open up the opposition.
As such, Matic's absence in this team will be a big blow for his Norwegian manager. He could miss up to three weeks, after picking up an injury in the build up to the Liverpool game. In his absence, Solskjaer has turned to McTominay, but in truth, very few players in the world could replace Matic in this team. As such, the Norwegian's prolonged absence will be a devastating blow to Solskjaer's plans.
