Chelsea head coach Maurizio Sarri is reportedly still angry after Ruben Loftus-Cheek suffered a serious Achilles injury last week.
The Blues travelled to the United States to play a Holocaust Memorial match against New England Revolution, despite having only just concluded their Premier League campaign.
The club's 3-0 victory was marred by Loftus-Cheek sustaining an Achilles injury, something which could keep the England international on the sidelines for the best part of a year.
According to The Sun, Sarri has been left fuming behind the scenes, with Loftus-Cheek having been in line to start against Arsenal in the Europa League final on May 29.
The Italian had been unhappy with the scheduling of the fixture, and the setback with Loftus-Cheek adds to Chelsea's fitness issues ahead of the showdown with their London rivals.
