If that’s how you want to view it then sure. If you watch football, you can see how important Jack is to the team. Bernardo also. Both players don’t assist or score a lot but only 1 gets attacked for it. Team functions better when both are on the pitch.
Bernardo spends 80% of his football at City in deep midfield.
Grealish plays left wing. Bernardo has won us loads of games on his own.
Bernardo does everything Grealish does and 10 times more.
Grealish goes through the motions.
