Basically, Manchester City dominated this match from the first half, but they always failed with a number of good opportunities. Brentford's defense was a big problem for Manchester City's attackers, then their lack of good finishing was also the reason why this match didn't have more goals. Haaland and Alvarez contributed to this important win, both being involved for Manchester City's only winning goal.
That's the matter.
Recently, Man City has not been very optimal in optimizing the chances they have. In fact, it was a lot of chances, continuous attacks were launched against the opposing team. But, they could only get 1 goal. This is the subject of ongoing evaluation from Pep Guardiola, about how this can end soon and they can return as strong and effective as before.
There is a slightly different situation from Manchester City's attack pattern but in my opinion apart from them currently losing a little momentum especially with the current declining goal productivity making the situation sometimes unexpected for Manchester City.
From the attack patterns and game schemes carried out to date there is actually no problem for them, it's just that the opposing club knows that they have to survive and secure a point in a match when facing Manchester City because after all if they don't force to do that and aim for 3 points then surely it is a difficult thing. Therefore, we can only see the strength of Manchester City in terms of the quality of attack and possession of the ball but their Strikers are covered by their movements, Manchester City will experience a deadlock just like in the last few matches where when Haaland was tightly guarded they could not do much because Manchester City's fulcrum (Haaland) was limited in movement.
