I think Arsenal has a better chance of beating Manchester City in their Premier League match on Sunday at Etihad Stadium. Three Manchester City players were injured while on international duty for England, and there are doubts about being ready for the Arsenal match. This will be an advantage for Arsenal. Arsenal will dominate most of that match because John Stones and Kyle Walker are among the injured Manchester City players.
As long as there are still replacement players for the line usually occupied by John Stones and Kyle Walker, I don't think Manchester City will immediately become weak because of this. Because the Manchester City coach himself will also think about this more seriously because remembering that the match is at Manchester City's home ground, the Manchester City coach will choose players who are more suitable to fill that line so that the match can be exciting and it won't be easy for Arsenal to win there.
Man City's back line may indeed be slightly weakened by injuries to Kyle Walker, Manuel Akanji and John Stones. But Man City still has some pretty good defenders in the second tier. It's just that this will not make Man City's defense completely strong as usual. Now it's just a matter of Pep Guardiola creating a better strategy to close the gaps that could appear in Man City's back line. Arsenal, whose level of attack has increased recently, can indeed be a threat that can destroy Man City's defense. It's just that Man City as the host usually always has higher motivation to win the match. But if Arsenal manages to win in this match then that will be an extraordinary thing for Arsenal because it will make Arsenal record 3 consecutive wins against Man City this season. And actually it's quite hard to believe. So I don't think this will happen.
