No, Inter is still want to keep Lukaku, but they just want don't want to spend huge money to sign him. It's all depend on Lukaku decision whether he want to join Inter or Juventus, Juventus have offer better monthly salary and higher bid for Chelsea. I think the reason is Juventus don't have any other good striker except Vlahovic, so Lukaku can be a substitute player. There's a rumor where Vlahovic will join PSG or Arsenal, so that's why they're looking for a new striker.
Its not true, Inter Milan have been withdrew for signing Lukaku after second proposal bid offer 35 million euro rejected by Chelsea, seems there are not option for Inter Milan push up higher transfer fees for signing Lukaku. Good respond from Lukaku after Juventus interesting, if can't reach agreement with Inter Milan seems Lukaku will play for Juventus next season but depend negotiation transfer fees due Chelsea have offer higher values for interested teams want to sign Lukaku.
Current rumor, Juventus's striker linked with PSG and Arsenal will be good news for Juventus sell him and use transfer fees for signing Lukaku, until right now Juventus not opening yet their proposal for signing Lukaku.
