Former Liverpool midfielder Don Hutchison is backing their move for Napoli defender Kalidou Koulibaly.

The Senegal international has been mentioned as a big money summer target for the Reds.

"I think if Koulibaly comes through the door and he plays alongside Virgil van Dijk, I think you wrap the title up right there," Hutchison, who spent four years at Liverpool between 1990 and 1994, told ESPN FC.

"I don't think there's anyone better, there won't be another partnership like it.

"The best defenders out there in Europe apart from the Premier League at the moment is Milan Skriniar at Inter [Milan], my gut feeling is he's going to join Pep [Guardiola] at Man City, and alongside him is Koulibaly.

"I think at 28 he's a great age, he's got good pace, he's strong, he's a leader.

"I think he walks straight into Liverpool's line up and he makes them harder to beat, he makes them a physical presence.

"You wouldn't want to play against Van Dijk or Koulibaly - how on earth as a striker as a striker do you even think about getting any joy out of those two?"
