I agree and Kevin De Bruyne is one of the most powerful midfielders in this game. I am a lucky person to see this guy play the game, he is like the Messi or Ronaldo of the midfield.
I also think de Bruyne is a very special player. But even without him, Manchester City win their matches. Manchester City have a very large and very high quality squad. They brought the best players in the world to the team and the best manager in the world is coaching them. The absence of a player is not felt. However, if 5-6 players are missing at the same time, there may be a problem. Apart from that, they have very solid rotations. For a team that plays around 70 matches a year, it's important to have strong squad depth. Manchester City management does this planning very well.
KDB is a silent achiever and because he doesn't glory going to media to make some noise some people tends to underrate his abilities in the field of play. Every good player and football lovers know the worth of KDB in every midfield. Guardiola himself understands this very well, that is why he doesn't joke with Kelvin.
Even anytime Haaland is interviewed, he doesn't stop emphasizing the abilities of Kelvin in the midfield. It is clear even to the blind the space Kelvin has left in the midfield of Manchester city. Should Kelvin be around, I do not think that Arsenal would be able to win Manchester city last week.
I wish KDB fast recovery so that he can rejoin his team for a greater performance.
