Chelsea will miss the services of Ruben Loftus-Cheek and Marcos Alonso when they take on Malmo on Thursday for the last-32 tie. 

The duo was not included in the squad's final training session on Wednesday morning and was not part of the traveling squad to Sweden. In his press conference, Maurizio Sarri confirmed Loftus-Cheek was struggling with a recurrence of the back injury that has hampered his season so far. 

Meanwhile, Alonso has been rested by the Italian coach after suffering a dip in form in recent weeks. It appears Sarri has decided to allow the 28-year-old a chance to recuperate after featuring in every one of Chelsea's Premier League games this season.
