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.
