'Koulibaly worst Chelsea signing and should leave in January' - Fans after Manchester City defeat

Koulibaly has to be the WORST centre back I’ve ever seen. - @ibzsmo3k

I got it wrong on Koulibaly I thought he’d be a brilliant signing for Chelsea due to how well he did at Serie A. He’s just so aggressive and goes all in and doesn’t have the physicality anymore to recover. He just strips against attackers nowadays. - @_halfspaces

They told us Koulibaly was top 5 CBs in world football. - @livzledgee

This Koulibaly is definitely not the “Napoli Koulibaly” Chelsea paid for!! - @burnarena

If I was John Terry I’d be ringing Koulibaly back and asking for him to return that shirt. - @CampoCFC

Koulibaly with all his experience is playing alongside an academy-level defender and he has managed to look like the Amateur. - @deoors

Koulibaly so far is Chelsea’s worst signing of the summer if you ask me. Mistimed tackles, misplaced passes, losing the ball easily, no coordination. It’s even suicidal to leave these young ones at the mercy of Koulibaly’s blushes at the back.

He’s closely followed by Auba though. - @Froshbanks

Koulibaly needs to go. - @EbereCFC

Koulibaly & Jorginho need to leave Chelsea ASAP!🤡 - @RobKirianki

The first major business from Chelsea next season is to let Koulibaly leave. - @comics_damires

It’s just criminal to allow Rudiger to leave Chelsea for this Koulibaly, it’s just shameful 🤦🏻🤦🏻🤦🏻🤦🏻 - @lekxyman

That switch from Rudiger to Koulibaly has to be one of the biggest downgrades in football history. - @omwanaballer

So lucky that we got Chalobah for free. He is better than Koulibaly, Fofana and Badishile! - @Kiswili_10

Chalobah is better than Koulibaly at the moment, no reason why he shouldn’t be starting in all honesty. - @CFCPys

All I have to say is may God forgive all of us that said Kalidou Koulibaly is an upgrade on Antonio Rudiger 😭 - @badboy_jeremy1

Rudiger was so key to success under Tuchel. Rudiger single-handedly started attacks. Koulibaly isn't at that level anymore to be able to do so. The attacker's confidence will come from knowing that any player in the team can/will try to pick them out at any time. That's hugely lacking now! - @MrGeorgeBenson

We genuinely lost Rudiger and replaced him with Koulibaly. Got it wrong, it’s a massive downgrade. - @GlorySake

We replaced Rudiger with KOULIBALY 😭😭😭😭😭😭😭😭😭😭😭😭 - @CFCKaz6

Koulibaly should’ve just continued in Serie A where we all assumed he was good without watching him 😭 - @UTDTrey

I think Koulibaly has been exposed. I think the Premier League shows exactly who is a world-class defender, in Serie A he looked phenomenal, an absolute shadow of himself since arriving in England. - @A1Chels_

Koulibaly is one of the biggest myths in football history. Serie A fans tried to convince us he was him. - @mxdric

Potter doesn’t have the ability to read games. How can you put Koulibaly who is fond of making mistakes alongside three inexperienced defenders to play Man City and leave Thiago Silva on the bench? We really need Tuchel back. - @mikel_spade

Graham Potter is our problem, if he continues to be our coach till the end of the season we will be relegated. - Ofori Amanfo

Potter has no formation and tactical knowledge to lead Chelsea. - Nathaniel Agyei Peprah Diffaral

Chelsea made awful decisions in signing these players - Koulibaly and Aubameyang - then sacking Thomas Tuchel for Graham Potter. Two wrongs at the same time. - @Kiswili_10

Aubameyang has to leave Chelsea this window. After being subbed in and subbed off in the same match, he’s not been included in the squad for today. - @sholashegun

It is time for some players to leave Chelsea, the likes of Koulibaly, Ziyech, Ruben Loftus-Cheek, Pulisic, and even Aubameyang. - @TobiasMurimi

Koulibaly needs to step up, he’s not worthy of wearing JT’s number 26!!!!! - Alison Bernia

Koulibaly always pulling opponents' shirts because you are soo slow and jittery every time he has the ball, he is not good enough and must step up... - Sydney Ngwerume
