I totally agree with you, friend! Juventus desperately needs to make some targeted signings to improve the team. Jonathan David is a great signing, but he can't lift the team on his own! In my opinion, they should sell Vlahovic and cash in as much as possible, then buy a midfielder and a striker.
Vlahovic should absolutely be leaving ASAP. The guy is no use for Juventus from now on. But the problem is, there is no official offer in Europe.
He has been offered to Newcastle in exchange for Tonali. But I don't know...Saudi Arabia could be his exit. However is there any team from there willing to approach him? If there is then this is a silver lining for Juventus. He is entering his last year of his contract there for now.
