I have a slightly different idea, Haaland is not the key factor that helped Man City win the championship. Erling Haaland is a small player in a big match, he always fails in the final.
EPL is tough because the elite and average club are competitive. Manchester City won the EPL title because Erling Haaland made good use of his goal scoring opportunities and also his teammates played a major role in game victories. Pep Guardiola arrange his strategy and every player played a role in accomplishing their targets, no one was left out. Erling Haaland is a top player and goal machine for Manchester City.
Erling Haaland doesn’t even have anyone who can compete with him in the Premier League in terms of scoring goals, it looks Premier League wants to become a farmers' league where one team will be winning the title all the time and also have a player that will always be the highest goals, scorer of the league, for me Manchester City have turned premier league to farmers league because they always want to win the title all the time, but that’s not their fault, the premier league teams are the one that we suppose to blame for their poor performances most especially arsenal that use to disappoint themselves by giving Manchester City a chance to win the league every season.
I haven’t seen any team that will step up to stop Manchester City from winning next season's premier league title, Manchester City has become a team that wants to win the title all season and from looking at their performances they are still capable of winning the league again, Manchester City still have young players that are going to join the team and still win trophies for them, Arsenal, Manchester United, Chelsea are just like a team that doesn’t know what to do next season because they are all confused about how they are going to win the league next season.
