Inter Milan are reportedly willing to sell their goalkeeper Andre Onana to Chelsea if the Blues extend striker Romelu Lukaku's loan and offer Kalidou Koulibaly in return.
Chelsea are interested in signing Onana as a potential upgrade on Edouard Mendy and Kepa Arrizabalaga.
Both Mendy and Kepa failed to cement their status as regular starters over the course of the recently-concluded 2022/23 season.
Onana, meanwhile, is part of an Inter Milan team that will face Manchester City in the UEFA Champions League final on Saturday.
However, Chelsea are tempted to bring the Cameroonian keeper to Stamford Bridge this summer and according to Italian outlet Repubblica, Inter Milan will let the deal happen if they get Koulibaly in return and extend Lukaku's loan spell at San Siro.
