Chelsea defender Kalidou Koulibaly is in talks with Juventus.

La Gazzetta dello Sport says Koulibaly is unhappy at Chelsea and taken a call from Juve coach Max Allegri about a return to Italy.

The former Napoli captain could arrive on-loan if he agrees to reduce his salary from €10m to €7m.

Allegri informed Koulibaly he'd like to "train" the stopper, who thanked him for his interest in a limited response.

Meanwhile, Allegri has also raised with sports chief Francesco Calvo about signing Chelsea striker Romelu Lukaku. Juve's idea would be to take Lukaku, currently with Inter Milan, on-loan next season with no purchase option.
