Napoli defender Kalidou Koulibaly is again being linked with Manchester United.

Gazzetta dello Sport says United are determined to sign a top centre-back to partner up with Harry Maguire at the back in the summer transfer window.

And United are still interested in Napoli ace Koulibaly.

Koulibaly continues to be in the Red Devils' radar despite the fact he turns 30 years old this month.

The Senegal international is said cost around £35million this summer.
