Manchester United will reportedly reignite their interest in Kalidou Koulibaly this summer after learning Liverpool are monitoring the Napoli defender.

Red Devils boss Ole Gunnar Solskjaer is understood to rate the centre-back, 28, highly and was tipped to sign the Senegal international after he was named in the Serie A Team of the Season at the end of last term.

Nothing ever materialised, with Solskjaer opting to fork out £80million for Harry Maguire instead.

Gazetta dello Sport, per Daily Express, reports that United made an £89m bid for Koulibaly last summer – but he could be available for a significantly cheaper price at the end of this season.
