Chelsea centre-back Kalidou Koulibaly failed to make the bench for Chelea’s 1-1 draw against West Ham on Saturday at the London Stadium.

According to Adam Newson of Football London, Koulibaly missed the game against West Ham due to illness as confirmed by Chelsea boss Graham Potter.

Newson tweeted: “Kalidou Koulibaly wasn’t in the Chelsea squad for Saturday’s game as he was ill overnight, Graham Potter confirmed post-match.

“Big decision ahead as to who replaces Benoit Badiashile in the defence against Dortmund.”
