Manchester City did win but it was a little worrying, especially against Luton they had to fight hard to be able to turn things around and win with a score of 1-2. Pep Guardiola's squad even had to concede first and against a weak team like Luton they shouldn't have given opposing players the opportunity to break into their goal easily.
On the other hand, Bernardo Silva and Julian Alvarez were key players for Manchester City in this match because they both managed to score the winning goal. After often getting unsatisfactory results, finally Manchester City were able to taste victory again and they had to achieve that against a weak team like Luton and I think that was quite disappointing.
We know Pep Guardiola to becomes very competitive coach that doesn't give room for anyone to give excuses. Luton Town gave the citizens hard-time today, defensive in all angles Manchester City could possibly put the ball through but atlast, they were able to record a comeback and grab Ed three solid points from Luton Town. If Manchester City continue like this, it will not be easy because there are more competitive contenders for the EPL title and Manchester City will turn out to become another club on the othe end that's struggling to earn points.
I understand and it is natural that a team like Luton will only use a defensive strategy against a strong team like Manchester City, but if they don't immediately look for gaps in the defense then Manchester City will also lose their chance to win. This problem should be resolved well and it won't take long to dismantle Luton's defense and Manchester City should be able to win with a difference of at least 2 goals. But what happened was that they only won narrowly and it was quite vulnerable to a draw if their defense was not ready to anticipate Luton's attack. But overall this is good but not good enough for future competition.
