Manchester City are one point behind Arsenal but it still lacks one more game in addition to the two last rounds so a total of 9 points comparing to gunners which only could collect 6 points.
Manchester City really needs Haaland in his best form. He can achieve some wins for Manchester City, where he can be a deciding factor. His ability to score goals is unprecedented and Manchester City's players are well adviced to search him, to give him scoring attempts and Haaland will likely convert to goals for Manchester City, which Manchester City really needs in such a tight battle.
I believe Haaland will be a deciding factor for Premier League.
Manchester City is a big team with good quality and as such, Haaland is not the only player who can bring victory to Manchester City. Because after all, when Haaland didn't play due to injury, but in reality Manchester City was still fine and managed to win the match. Also, Haaland does not always manage to score many goals in every match and thus, teamwork is the main key to the team's success and it is not just about Haaland to making Manchester City win. LOL! But indeed,the reality is that Manchester City still has a very big chance of winning the Premier League trophy this season eventhough currently Manchester City is still in second place. But after all, Manchester City also still has one match postponed and thus, Manchester City still has a very good chance.
