Inter have also recently submitted a second bid for Lukaku that they offering 35 millions plus ads on and it will be their highest bid for him because Inter is not dare to buy Lukaku beyond that price and Lukaku hasn't respond it yet whether he will decide moved to Inter or he will reject that offer and when Juventus are joined the race to get him apparently Lukaku a bit doubt about his decision whether he will moved to Inter or Juventus especially after Juventus was offer a higher bid compared to Inter
Lukaku has been make a statement last month that he will give his priority for Inter because he felt comfortable while playing at there and i think he have to showing his commitment and choose Inter rather than Juventus especially Juventus offer is also still uncertain because they have to sell Vlahovic first to another team
Its small difference than first bid offering with 30 million euro, I don't think Chelsea interested with second bid offer from Inter Milan 35 million euro because they want sell most expensive price due Inter really need Lukaku. Inter Milan looks not tries with third bid offering because they won't spent much money for Lukaku and looks he will ne as priority for Pochettino. Beneficial for Juventus are the race for signing Lukaku because they will offer higher offer than Inter Milan.
Current squad, Juventus still has Dusan Vlahovic as center striker and they are waiting for until success sell Vlahovic to interested teams like Manchester United and PSG, but if failed sell Vlahovic I don't think Juventus want to sign Lukaku from Chelsea.
