Juventus are keen on having Lukaku after seeing Vlahovic's performance last season. Chelsea shouldn't give up on this deal as it would be a reasonable deal for them. It is obvious they can't do anything with Lukaku. Bringing Vlahovic is a chance to keep their attacking line more productive.
I don't think if Juventus even think about Lukaku, because there was some news about Dušan Vlahović leaving this team soon to other teams and we know Dušan Vlahović is an important player for Juventus but since they don't have a good financial situation even Allegri did say a no when they asked him about Vlahović, he said rejecting some offers is impossible because of their current financial situation which means we are going to see Vlahović leaving Juventus soon and play in another team in the next season.
His contract is still up to 2026, is it true that he will leave Juventus?
I consider that maybe Allegri's decision was not good enough for the progress of Juventus even though Dusan Vlahovic's departure might improve the club's finances but without him I can't imagine what Juventus will be like for their attack line.
Allegri should really reconsider on this matter.
