Vlahovic, a 25-year-old Serbian international, is reportedly unwanted at Juventus. The Serie A side has given him 15 days to find a new club.
Newcastle and Barcelona have been linked with a potential transfer, but neither club has made an official bid for the striker.
Vlahovic's agent believes staying in Italy would be the best option, citing support from the coach and teammates. However, the striker was recently booed by Juventus fans in a pre-season match.
Juventus is looking to sell Vlahovic to generate funds for their attacking options. The club is seeking to revamp their team and make some changes to their lineup.
