Manchester City handed Chelsea their third loss in four games by beating the Blues 2-0 in the EFL Cup third round.
Riyad Mahrez's excellent free-kick opened the scoring early in the second half before Julian Alvarez doubled the Citizens' lead five minutes later with a predator's finish. Chelsea should've taken the lead through young left-back Lewis Hall just before half-time, but City goalkeeper Stefan Ortega denied him in a series of impressive saves on his night to shine.
Graham Potter, on the other hand, had a much more miserable night, with his Chelsea side stuttering after a promising start to his tenure. The same can't be said for this relentless City team, though - even without Erling Halaand - who're looking to reclaim the EFL Cup in 2023, a favourite trophy of Pep Guardiola's.
