I think there is a huge chance that he will be sold in January. Basel just signed a very talented striker from Slovenian league, Andraž Šporar ('94, 17 goals 5 assists in 17 games), for 3 million € and they also gave him #9.
We own 0% of Berardi. Nor do we have any explicit exclusive first rights to negotiate with Sassuolo to sign him. It's basically only a gentlemen's agreement.
Wolfsburg were heavily interested last season and Allofs has been working on that deal since. Bild reporting that coach Hecking will get his wish and Embolo moving to them in winter. The fee could be between 25-30m€ and Basel r prob buying Slowenian striker Sporar as his successor.
Embolo is a great player but we should take notice that this guy is not a goal machine but more of a great forward who can dribble score is fast and has some muscles in him - He might be WC in the future and he can surely get there but we should also understand he is not WC yet and if we do get him (we wont but still...) we shouldnt expect him to be a Cavani or Higuain in terms of scoring!
