It Manchester United want Kalidou Koulibaly from Napoli this summer, they are going to have to pay through the nose.

Not only will United have to cough-up a nine-figure fee to sign the defender, but they will have to shatter their transfer record in the process.

It will take £110million to make Napoli consider letting Koulibaly leave.

In January, Old Trafford bosses thought a deal could be done at around £80m.

But according to the Sunday Express , nothing is happening unless any club meets their asking price.
