Bayern Munich are preparing a bid for Napoli defender Kalidou Koulibaly.

Koulibaly is a top target for Chelsea and last week invited controversy by talking up the prospect of playing for Antonio Conte in London.

BILD says Bayern are also interested and willing to offer €30 million for the defender.

Napoli have not formally placed Koulibaly on their transfer list, and it's suggested they won't consider cashing in.

However, such is the tension between the board and the player that a split appears inevitable.
