Chelsea have warned Napoli they won't go higher for Kalidou Koulibaly.

The Sun says Blues have been dealt a blow in their pursuit of chief target Koulibaly with the Senegal defender set to snub a move to Stamford Bridge and sign a fresh deal with Napoli.

The London club are now believed to have told Napoli that they have lodged their final bid and moved on to other targets.

Chelsea lodged a major bid for AC Milan defender Alessio Romagnoli this week.
