Five Reasons Chelsea Haven’t Won The Title Yet, Including Manchester City Resurgence And Diego Costa Injuries

3) Reliance on Nemanja Matic

The Serbian is very important to how the Stamford Bridge outfit set up. It is his defensive work that allows the rest of the midfield to play in the free flowing manner which they do. Were anything to happen to him such as an injury or a drop in form, then it would be interesting to see how Mourinho copes. Ramires can perform a similar role in the middle of the pitch, but is not as effective as the Serbian.
