Manchester City's suspect defence was on show for everyone to see once again against Chelsea.
Pep Guardiola's side dominated the game at Stamford Bridge, creating a plethora of chances, but their ineptitude at the back saw them defeated 2-1.
Benjamin Mendy's mistake for Christian Pulisic's opening goal summed up City's defensive woes in 2020/21.
Even with Aymeric Laporte back in the team, Guardiola's side still look vulnerable. If they're to compete with Liverpool next season, they need reinforcements - despite the fact they've spent millions on defenders in the past few years.
It's an avenue City are already pursuing, because they're actually currently in negotiations to sign Kalidou Koulibaly from Napoli this summer.
Club journalist Sam Lee confirmed the news on Twitter, replying to a fan asking about the Koulibaly rumours: "Yeah, I don’t know what stage they’re at with negotiations but they’re working on it."
It's been widely reported that Napoli will be selling the 29-year-old defender and it seems City are now the favourites to seal his coveted signature.
On the face of it, the signing of the Senegalese could potentially galvanise Guardiola's team in a similar manner to how Virgil van Dijk did at Liverpool.
Every other area of City's side is functioning as well as ever, but their defence needs a serious reboot.
Fernandinho has his flaws at centre-back, while both John Stones and Nicolas Otamendi are simply not good enough at the moment to warrant a starting role at a top team.
Signing Koulibaly really could be a game-changer for City. Watch out, Liverpool!
