Kalidou Koulibaly's agent has reportedly arrived in Manchester with the view to negotiating a move to Manchester City.
The Senegal international is thought to be a leading target for the Citizens during this summer's transfer window, but Napoli are refusing to sell unless their valuation - thought to be as high as £90m - is met.
According to Corriere dello Sport, the centre-back's agent Fali Ramadani has travelled to England in the hope of securing a move for his client to the Etihad Stadium.
City have already boosted their back line ahead of next season with the signing of Nathan Ake from Bournemouth.
Head coach Pep Guardiola is still believed to be keen on at least one more defender arriving at the club before the October deadline, though, as they look to wrestle the Premier League title back from Liverpool next term.
Koulibaly, who has previously been linked with Manchester United, Barcelona and Real Madrid, still has three years left to run on his contract in Naples.
