We expected Arsenal to learn from their previous mistakes after finishing second in the league for two seasons in a row, but the squad was not ready to take their opportunities last season when Manchester City, who normally dominate the league, were not in top form. Liverpool won the league title this season with 84 points, but it wasn't enough for the league dominating team. Arsenal did not play to their full strength, otherwise, last season may have been their best chance to win the title. If Manchester City were in top form, I doubt they would win the league with 84 points.
However, predicting what will happen next season will be tough because every team is active in the market, signing top players who can improve their performance the next season. If Manchester City can return to winning ways at the start of the next season, it will be difficult for Arsenal or Liverpool to win the league, however, if Manchester City performance remains as poor as it was last season, Arsenal may be able to win the league if they can compete throughout the season.
Arsenal's major problem last season was that their attacking line became weak due to some players injuries, and there was no perfect replacement for their injuries players. To me, major players like Bukayo Saka, Jesus, and Kai Havert were the key players in Arsenal that always made the attacking line strong, and their injuries contributed to their poor performances at the end. Similarly, Gabriel Magahes is the team's outstanding defender, and his injury make the central defense soft.
There will be a great challenge in the EPL this coming season because all top 5 clubs are boosting their squads by bringing new names to the club but My prediction for the EPL trophy is that either Manchester City, Arsenal, or Liverpool will be the favorite to take the trophy, specifically Liverpool because I haven't see any improvement from Manchester City to compete for the EPL title.
