Midfielder Chelsea Willian injured hamstring.
The Brazilian midfielder was in the starting lineup for the match against Arsenal in the English League Cup. At the 30th minute he left the field due to damage.
Chelsea head coach Antonio Conte said that the replacement of Willian was caused by problems with the back of the thigh.
"Villian's injury was one of the key moments of the match, as we did not have many opportunities to replace him," the official site of Chelsea quotes Conte. - Morata today could not play, and therefore the decision to release on the Ross Barkley field was to some extent forced ".
Recall that the "blue" lost to the "Gunners" and failed to qualify for the League Cup final.
