This is where the Role and Position difference comes in.
Positionally, Bernardo may start as an RW but he's not a wide player so he'll naturally drift inwards into number 10 type positions and areas. Nothing like Dembele.
Barca need a winger with pace who can take players on or stay a lil wide.
If they could afford him, Raheem Sterling would unironically be a very good signing since he has an amazing burst of pace and can take on players and even hug the by-line and play.
Sterling has no vision and no final ball .. he is a tiny version of Adama !
He secured goals but all tap ins courtesy of KDB , Mahrez , or Bernardo Silva
