I don't think De Bruyne's importance at Mancity can be greater than Rodri's. Remember that some time ago, Mancity lacked Kevin for a long time but they still played well if Rodri was still in the squad, but when Mancity was without Rodri, they continuously encountered difficulties with defeats. I do not deny the importance of De Bruyne in Mancity as he is an important link that helps Mancity's attack explode. But without Rodri, both the midfield and defenders will have problems and the hole he leaves behind is huge. Without Kevin in the upcoming match, Mancity will have a lot of difficulty scoring goals, but Arsenal is no better when the two main strikers, Martinelli and Saka are also in pain and not sure can play or not.
People always take a look with the results and statistics, but they didn't pay attention with the impact of the player and how the player gives contribution on the pitch. Rodri is the best all rounder player, his ball control is above average, has a good shooting skill, can play under pressure, has a tackling skill and can build up. He's just underrated, I'd say he should be worth more than Haaland and De Bruyne.
