Chelsea boss Maurizio Sarri admits it was a tactical decision to leave Ruben Loftus-Cheek out of his squad to face Arsenal on Saturday.
The 22-year-old was not included in Chelseas 18-man squad to take on the Gunners, who had Marcos Alonso to thank for a late winner in a 3-2 win at Stamford Bridge.
Loftus-Cheek was linked with a move away from the club before the tranfser window closed and it appears unlikely that he will get the playing time he wants following the arrivals of Jorginho and Mateo Kovacic.
And, in perhaps a worrying sign for Loftus-Cheek, Sarri has revealed it was purely a selection decision to leave the midfielder out against Arsenal.
It depends on the position on the pitch, said Sarri, when asked why Loftus-Cheek was not included.
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.
