The Serie A giants are keen to land Lukaku and are offering Dusan Vlahovic in a swap deal.
However, Juve are also demanding a €40m fee as part of the transfer.
Chelsea are yet to make a final decision on the move and it is believed new manager Mauricio Pochettino will be “crucial” in making the call.
