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.
Sometimes, it won't be easy to win against the teams in relegation zone. I don't think we need to feel worried, Man City still succeed to win the match at least. Although Luton Town scored first, Man CIty could scored 2 goals later. Man City showed their winning mentality, they could handle the situation during the match.
Bernardo Silva contributed with a single goal, he also becomes a player who has a big role in the match. I'm quite happy that Bernardo Silva can play better and gives contribution for a win. This can be the beginning that Man City can have a proper replacement for De Bruyne's role as an attacking midfielder. Man City loses this role so far.
