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.
In my opinion, the problem lately for Man City is the finishing, no player can do that right now, Haaland is having a hard time as a striker because there is no reliable passer behind him, because if the problem of ball possession and opportunities for Man City still dominates its opponents, then indeed in the transfer market later Pep must do something by bringing in several players to stabilize the strength of his squad so that it no longer experiences ups and downs in performance in the matches that will be played.
