Juventus have raised a swap deal with Chelsea for Dusan Vlahovic.
Il Corriere della Sport says Chelsea have approached Juve about a price for the Serb.
And Juve have responded by raising the idea of an exchange involving Romelu Lukaku.
Juve would be willing to offer Vlahovic to Chelsea in exchange for Lukaku plus 25m cash.
Inter Milan are also in contact with Chelsea about a permanent deal for Lukaku and had a 40m offer turned down last week.
