Chelsea midfielder Loftus-Cheek failed to make the bench as Chelsea beat Arsenal at Stamford Bridge on Saturday.
Asked why Loftus-Cheek failed to make the bench, Chelsea boss Maurizio Sarri said: “It depends on the position on the pitch.
“I prefer to have on the bench two wingers, and only one midfielder. So it depends on this. Not any other situation.
“I needed on the bench one goalkeeper, one full-back, one centre-back, maybe two midfielders and only one winger, but yesterday I preferred vice versa, two wingers and one midfielder.”
