I wouldn't doubt if Arsenal will be able to win the premier League next season because in as much as most people feel that they did not play well but truly they actually tried their best but still let's not conclude that Arsenal will be the right candidate for the premier League next season because in as much they have a good performance their are also club that has more to offer such as Manchester City, so for now I think Manchester City will be their serious rival considering the fact that their players are now intact, Kelvin de Bruyne and the rest are very ready for the next season, so their is no way we are going to be sure on the right candidate now because considering the speed Tottenham Hotspur had on this season when they were unbeaten you would almost believe that the premier League belongs to them but look how everything change, so perhaps previous performances has proven that sometimes the club we feel that will performance well could become a struggling team when the time will come.
No one knows what will happen to Arsenal next season, it could be that they will be better or worse and we also haven't seen the transfer movements of these teams, but we can make a little prediction because in the last 2 seasons Arteta has succeeded in building the Arsenal team. is much more developed so this is also possible for next season.
Regarding winning the Premier League title, it is not easy and we can see that there has always been quite fierce competition, and I think it is not only Manchester City and Arsenal that are worth considering but there are also several other teams that are worth considering and in terms of percentages everything is not much different.
