To win the Premier League is not easy, this is a competitive competition so the competition is very fierce with the best teams who have almost equal quality.
Mikel Arteta has been building Arsenal in the last few seasons and has seen quite positive progress in each season so I don't deny that if someone says that they are candidates for champions next season, and the betting market also places them with Man City, that's normal.
Arsenal really deserve to be considered to be champions next season, as long as they can be consistent with the performance they have shown in the last few seasons, because if not then they will fail again. However, Arteta has sufficient capital now in his squad, because he has players who have been together for a long time, so he will be able to rely on them to provide a good team collective game using the chemistry they have built in the last few seasons.
He also has the opportunity to bring in new players to add to their ammunition next season. and so far I think the recruitment carried out by Arteta has also been quite successful, or in the sense that he has brought in players who can ultimately contribute to the game. He will also definitely be careful in deciding which players he will bring in, because that will determine whether the new players will make a big contribution or not.
Manchester City, which holds the status of defending champion, must be very careful.
