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.
I dont know what player can currently replace him on that position with the similar quality. He has been the brains behind a lot of attacks of Man City in the previous season and without him this is gonna cause problems. We seen already against Sevilla that there were many problems in getting that direct ball for the goal.
I can't really figure a player to replace him at the moment of his absence but there have got to be tons of players who fits in well. James Madison is a player who can fit in well but unfortunately he's signed as a Tottenham Hotspur player.
Newcastle had the best defense defense last season and they seem to be doing so already this season with a good start. No KDB, who step's up for him? Bernado Silva I guess and then Kovacic alongside Rodri for the midfielder's still, they're not creative and quality enough.
Manchester City are currently making advances to get the Brazil international Paqueta's deal done, West Ham rejected the first offer, second bid in line.
