I agree, I usually don't like over rating some of the young talents out there, but anybody who watches his games (and not just highlights) will see an intelligence and gracefulness that is rarely seen at such a young age.
The bonus to us is he can play Left Wing (Sanes spot) or Left Attacking Midfield (David's spot if Sterling goes LW)
The fact that he can play both of these roles future proofs our team and gives us great balance.
If we buy Maguire(or De Ligt), Rodri and Felix, we will have:
---------------------------------------------Aguero/Jesus
Sterling/Felix----------David/Felix/Foden--------Kevin/Bernardo/Foden-----------Mahrez/Bernardo
-------------------------Zinchenko/Rodri----------Gundogan/Dinho
--------------------Laporte/Maguire--------Stones/Magure-----------Walker/Stones
I think this is a great set-up for next season, maybe promote a 5th choice CB from academy as backup or buy De Ligt (but I doubt this)
If Rodri or Dinho are playing, then one of them can simply slot into the defense to make the 4 man backline that Pep uses; or
As usualy, if Zinchenko plays he just goes left back to make the back 4. I feel having BOTH options will be useful to Pep.
