Determined to start the season with three at the back, Arsène Wenger might need a bit more depth in defence, and it seems like he’s having a look around for a new central defender.

At least, that’s what TuttoMercatoWeb are claiming on Monday, as they reveal in an exclusive on their website that Arsenal have enquired about Napoli’s Kalidou Koulibaly.

A target for Chelsea last summer, the Senegalese defender signed a new deal with the Serie A side after the transfer window shut, committing his future to his current side for the foreseeable future.

Since then, the stories have been always the same: he’ll only go if Napoli receive an offer they can’t refuse, which would be upwards of €55m.

Well, the aforementioned Italian website state the Gunners have made tentative enquiries to the player’s entourage to see if he would be interested in a move to the Emirates at Arsène Wenger’s request.

Unfortunately for them, the answer appears to have been a firm ‘no’, described by TuttoMercatoWeb as the ‘blue wall’, as Maurizio Sarri sees the Senegal international as one of the key components of his team.

With Per Mertesacker set to retire at the end of the season, and just Gabriel, Rob Holding, Shkodran Mustafi, Laurent Koscielny and maybe even Callum Chambers for three spots at centre-back, perhaps some strengthening is required.

We’ll have to wait and see if Wenger finds the right man for the job this summer or not.
