There are rumors that Man United is also interested in signing Ryan Gravenberch. We all know Pogba still hasn't signed a contract extension at Man United, so it's only natural that Man United is also preparing some alternatives, such as trying to sign Ryan Gravenberch. If so many big teams are very interested in Ryan Gravenberch then it's very likely that Ajax will set a high price for him.
Regardless of who will be able to sign Ryan Gravenberch, I think this player will be able to shine even more because he is still young and has a slick talent.
Regardless Pogba stays or leaves the team, Man Utd needs good players for their midfield and that's a fact. Indeed Gravenberch is a good option not only because is young hot talent but also because his presence can "trigger" a better Donny van de Beek. Still, Gravenberch is very young to be considered as a first liner for Man Utd, and let's not forget that his manager is Mino Raiola, who is Pogba's manager as well...
I do not think Paul pogba will renew his Manchester United contract, he has been wanting to leave the club for the past couple of seasons, if his contract expires at the end of the season, it would be just like a free ticket away from the club. And I think juventus will be happy to have him back because he was one of their best midfielders at a time before he made a transfer to Manchester United, and since then things hasn’t really gone as he expected. There are other big clubs who has interest in getting the signature of the World Cup winner.
