Liverpool are certainly a tough team, the only one with full points.
Chelsea also have a good chance in my opinion.
Arsenal have potential but are unlucky and easily discouraged in my opinion.
I honestly see Manchester City out of the title race.
As long as Pep Guardiola remains the coach of Manchester City, we can't totally write them off from the Premier League title race. Manchester City may not lift the PL title, but the top 4 position, they won't miss it. They will find their way up there before the end of the season.
In my own predictions, the top 4 positions will be between Liverpool, Arsenal, Manchester City, and Chelsea. This downplay of Manchester City will only be for a while, won't last to the middle of the season, for Manchester City to bounce back
