It sems like that arsenal was winning the game easily, as an opening match and it was getting dominated by arsenal. I can't say if crystal's midfielder and defender were not good enough caused by the players in arsenal and crystal ahs different capacity. Arsenal was also still on its best performance when entering the season. If arsenal was getting easy win for that match and i would not be surprised to see that happened with such team.
Crystal must learn how to build its team become even better and better. Its team needs more time to compete with a club like arsenal.
Arsenal has made a good step for this session, they win easy 0-2 versus crystal palace without reply. This is a different case from the previous opening match where they lost 0-2 versus Brentford. So when we look at how they won and prepare for the competition, Arsenal has opened the chance for the title and is ready to compete with a strong clubs like ManCity, Liverpool, and Chelsea. Arsenal also gives the fans hope to be better in this season.
