The reason why in the first meeting Arsenal managed to beat Man City was because they were without De Bruyne who was injured and the match also took place at Arsenal's home ground. Now Man City's strength is so complete and they have the advantage of playing at home so I think it will be much more difficult for Arsenal to beat Man City. The tension of the match is also different because it is a fairly important match for the start of the title this season so both of them will play quite carefully.
If Arsenal loses then their chances of winning the English league will be smaller, unless they can hold a draw or win the match. This will be a big match in the English league because there are bets on who will lose or who will win. But even so, I am more confident that Man City will win the match because they are playing in front of their own crowd.
I agree with your reasoning there, it was a home game for Arsenal but in fact it wasn't just about De Bruyne. Pep Guardiola has difficulty making his squad appear impressive because Arsenal really has an effective strategy. Arsenal built a lot of attacks, they appeared to press and created more goal chances than Manchester City and in the end Gabriel Martinelli's 1 goal was enough to secure 3 points for Arsenal even though it came a few minutes before the end of the match.
But this time Manchester City is different. They will play at home and the squad is also complete compared to the first match at the Emirates, but it is still difficult for us all to predict the result. Manchester City is the favorite of many people, even the bookies also favor them because of their performance, but once again that is not any guarantee of getting Manchester City to win over Arsenal. There is only one team that will win if the two do not draw, but Arsenal's chances of winning are very low.
