Of course, most clubs with poor performance challenges will use the opportunity to bring in new players when the transfer window opens. Nobody can predict City performance because they are still playing in their shadows. Their last two victories does not guarantee a win in their next match. Pep needs to put his men back in form.
Manchester City is still in an unstable situation, I agree with you their 2 wins in the last 2 matches are not a guarantee that they will be able to achieve the same thing in the next match. We also remember some of the previous matches they also got wins, but after that they also had to accept defeat even in a row. Pep has been here for a long time, so he should have been able to detect what is the source of the problem of the team he is handling. then in the transfer market he can bring in players who can make a big contribution to the team's game. Actually their squad is still a good squad, even in terms of chemistry they should also be good because they have been together for a long time and there have been no major changes in the squad.
Pep Guardiola has been there for so long which you are quite correct but remember that those players are not getting younger anymore and I believe the performance they had in their last 2,3,4 seasons can not be compared to this season, this includes Pep himself because the strength he has in shouting to motivate the players is also going down, Pep had have a good reputation and good legacy to be proud of. I will advise him to retire before the age took him, i think he should consider moving to Brazil or any team that give him an offer. Manchester City had two consecutive victories which was a good achievement for them after a long period, let see how their next match will be against Brentford.
