Manchester City will test Napoli's resolve over defender Kalidou Koulibaly by offering them Nicolas Otamendi and Oleksandr Zinchenko in exchange, according to reports.
The 29-year-old is set to be hot property this summer with City joining rivals Manchester United in keeping tabs on him, but any interested party can expect to shed out a hefty sum to convince the Naples side to sell.
Koulibaly is considered as one of the best centre backs in the world and has enjoyed a stand-out few seasons in Serie A. But as he edges towards his thirties, time could be running out for the Senegalese star to turn out for a big club and win silverware.
