Do you know how long Kevin De Bruyne have been away for Manchester City? If I'm recalling correctly, he's been out Injured since the Super Cup finals against Sevilla and during that game he didn't play for too long, no direct contact was seen from any player and someone here be saying we evil for giving our own opinions on matters. If they're not mature enough to ignore things, they should try not to become a prick.
For long term plans, I feel like they should plan ahead for a possible replacement. Check the performance of Erling Haaland, is it same as that of his first season? He has the best passes and combination from Kevin De Bruyne. He be still the leading goal scoring player but has seen a drop also struggles with his goals and contributions.
Even top teams with big finances are not always able to play at the highest level, recessions are a normal phenomenon and this is normal not only for the team but also for the players. Haaland showed excellent results in the previous season and set many records, do you think it’s so easy to exceed your achievements every year? Don't worry, Guardiola is a great coach and if he needs new players he will find them.
