Manchester City have launched an opening bid of £57 million ($75m) for Napoli defender Kalidou Koulibaly – as The Sun reports.
The Blues are prepared to include bonus payments in the final deal, but the Italian giants are likely to hold out for a lump sum of £63 million ($82m) upfront.
Pep Guardiola has already added Nathan Ake and Ferran Torres to his City ranks, and Koulibaly could be the next man to arrive at Etihad Stadium this summer.
