I don't think Arsenal are too pleased with their win, like many they were just testing tactics and some players, everyone should realise that's what pre-season matches are for, not to satisfy their egos with wins. Most teams don't even put half of their main squad on the pitch in such matches. But it's definitely worth saying that Arsenal are feeling good about themselves
Yeah you are right, at least the coaches know which strategy is right for them. There are positive things that can be taken and there are also negative impacts for the positive thing of course they think that they can play well for negative impact they can't evaluate the team I mean to find the weak side. Overall I hope Arsenal can continue to play well to compete with Manchester City next season because I want to see the new team as a winner.
Pre-season matches will certainly evaluate the coach's strategy, this is to test the players about mentality and see the game because every player the coach must know where the right position is to do in the League match later.
At least in pre-season matches Arsenal did not show a decline, especially with several players already brought in by Arteta, therefore the point of weakness can be overcome and when competing with Man City they are ready with everything that happens when they meet.
