Pogba will have been convinced man utd is the right place to be silvestre

I think there may be a slight misunderstanding!

Paul Pogba is a professional footballer who currently plays for Manchester United, but he didn't have a conversation with Silvestre (who is a former Manchester United player) about being convinced that Manchester United is the right place to be.

Silvestre is a retired French professional footballer who played for Manchester United from 1999 to 2008. He is not a current player or a coach, so it's unlikely that he would have had a conversation with Pogba about his decision to join Manchester United.

Pogba joined Manchester United in 2016 and has been playing for the club ever since. He has spoken publicly about his love for the club and the city, but I'm not aware of any specific conversation he had with Silvestre about being convinced to join the club.
