Antonio Conte’s woes have worsened with Victor Moses facing at least a month out with injury.
Chelsea’s hamstring jinx has struck again with the winger limping off during Saturday’s shock 2-1 defeat at Crystal Palace.
He is the third Chelsea star to be crocked by a hamstring pull in the last fortnight.
Boss Conte declared the problem an ’emergency’ as he tries to fill the gaps in his team in a busy October for the defending Premier League champions.
Chelsea suffered their second loss in a row at the weekend and Moses joins leading striker Alavaro Morata and key midfielder N’Golo Kante with hamstring problems.
In Moses’ case the player could be out for up to six weeks during a hectic run of fixtures with Champions League and Carabao Cup games sandwiched in between the defence of the title.
Moses joins the sick list at Stanford Bridge just as Morata has resumed full training.
The Spaniard sat out the defeat at Palace but should be OK to play in Wednesday’s European tie at home to Roma.
Meanwhile, their Italian opponents are facing an injury crisis ahead of the midweek showdown.
Chelsea could be up against a second-string Roma side after star defender Kostas Manolas was forced off during Saturday’s defeat to Napoli with a thigh strain.
Eusebio Di Francesco is already missing a number of first-teamers including Stephan El Shaaraway, Patrik Shick, Kevin Strootman, Gregoire Defrel and Emerson Palmieri.
They may now be without Greek international Manolas, who forged a rock-solid partnership with now-Chelsea centre-back Antonio Rudiger last season.
Roma are also sweating over midfield whizkid Lorenzo Pellegrini, who was forced off against Napoli as well.
