I see the loss of the figure of Kevin De Bruyne greatly affecting the performance of the Manchester City team, their front line is not well organized and there is not enough supply of balls for strikers, this is dangerous for Man City in the next match because they will lose Kevin De Bruyne who is absent for 6 months due to injury.
You are right, so far Kevin De Bruyne role has been very important in building Manchester City's attack. He has been likened to the brain of an attacker who can read the opponent's gap, but now Manchester City losing him for several months is a bad sign. In my opinion, it is very difficult to replace the role of Kevin De Bruyne, therefore Pep Guardiola must think hard to find other options. Especially after losing Gundogan when he was still at Manchester City he could replace Kevin De Bruyne.
