Well it's obvious that the absence of two players Kelvin Debruyne and Rodi has contributed to their poor performance and this should let Pep Guardiola to know that the team still needs strengthening,
Yes mate I think Manchester city are suffering from extreme injury problems and the match against arsenal exposed how even them can fall without the right players, they are missing Kevin and some players are playing the wrong roles or aren't playing in their natural position.
One of the biggest mistakes they made was to sell some very important players and they didn't improve their midfield
Of course, Man City is really suffering due to injuries to several of their key players. It cannot be denied that the absence of Bruyne and Rodri will have a big impact. They may still have Haaland and several other top players to strengthen the team. but we all know how important the contribution and importance of these two players, especially de Bruyne, is to the team. The hamstring injury he suffered several months ago is even expected to continue until the end of the year. Not to mention after he recovers, we don't know whether his performance will be the same as before or whether there will still be differences. Because we know that if someone suffers a serious injury, Usually, even though they have recovered, their performance will not be as optimal as before and they are prone to re-injury. Hopefully this is not true and de Bruyne can really play optimally like before when he returns. What is certain is that Pep Guardiola currently really has to work hard so that they can survive and improve their performance even without these two players optimally.
