2. Utilize cup-tied players in the Premier League
Matic has been a regular started for the Blues ever since his big money signing, hence giving Mourinho the option of saving Ramires or Luiz for the UCL. As Chelsea don’t have him in the UCL because of him already playing for Benfica, they have become heavily dependent on the Brazilian duo. But since Mourinho has established Matic as a first team regular, one of the central midfielders can take a breather alternatively.
Now, however, the time has come to utilize Mohamed Salah fully. Salah’s performance against Stoke where he had contribution in all three goals speaks for itself. Salah can effectively replace Oscar, Willian or Schurrle and with Eden Hazard out for two weeks because of injury, Mourinho will have to use Salah more often than he would have thought. This policy of squad rotation will provide good rest to the first-team attacking midfielders so as to make them ready for the UCL. Mourinho used this thought against PSG as he had rested Oscar against Stoke and the Brazilian performed much better than some of his previous tired displays.
