I'm quite surprised to see how City were beaten by a team like Brighton. They should have won this match, but somehow lost momentum in the second half. They were dominant in the first half and even scored the opening goal through Haaland. However, their defense was poor, and they lost their rhythm, which ultimately led to their defeat.
Guardiola himself lamented City's loss to Brighton, emphasizing that the new players had not fully integrated, which caused a lack of balance in the game and contributed to the defeat.
But I don't think this is a serious problem for City, because they can definitely improve and bounce back in the next matches considering the quality of the squad they have and Guardiola's experience in managing the team.
