I hope he is Rodris backup, because nobody else in the squad is better suited for it.Got unfairly left out last season to the detriment of the team imo to enable Pep to shoehorn more attacking players into the side, for large parts of the season we didn't play anywhere close to the level we've been at in recent years but our best most fluid football almost always came when we had kovacic in the side.
He will prove invaluable to us this season. we can expet marked improvements from kovacic, gvardiol and doku with a year under their belt now.
Just hope Pep doesn't ask him to be Rodri's alternative because he simply isn't suited to that role, never has been at any of his previous clubs and isn't going to change at this point in his career.
He also isnt suited as a #8 for us. Pep had to adapt to Kovacic qualities by going with wide fullbacks, so Kovacic didnt have to push up, and he stayed deep, instead the wingers came in.
I personally hate the wide fullback system, bring back wide wingers and have Bernie/Nunes/Rico partner Rodri and then push higher.
