The defensive line of manchester city is very weak as it was always conceded so many goals. Pep needs to do somethings. I think that he needs to make sure his club will be able to get three points again.
Manchester city needs to keep up with the team like arsenal and liverpool which are still facing easy schedule. Pep needs also to buy the new defenders.
Im thinking that manchester city needs a new centre back. It was also need to replace walker with a new good RB.
Manchester City tried to improve their defense and invest in future with Gvardiol transfer from Leipzig in the summer transfer. The Croatian defender had some good seasons with Leipzig and an amazing World Cup 2022, that convinced Manchester City to spend huge transfer cost to bring him to Ettihad from Leipzig.
So far, it seems Gvardiol has yet adapted too well with a new club and Premier League. He is struggling to adapt to intensity of Premier League matches and speed of players in the league. It's too soon to consider he is a failed transfer and I think we will have to wait for his second season in Premier League to assess Gvardiol more accurately. One season for adaptation is not too much for a big and competitive national league like Premier League.
