Even though the new season hasn't started yet, I believe Manchester City, Arsenal, Liverpool and Manchester United have a big chance to be the favorites for the title. The main favorites are Manchester City, followed by Arsenal, but I doubt the other two teams I mentioned as well.
Last season, no one knew Newcastle United will qualify for the champions league this upcoming season. We can’t be so exact in our assumptions of the best 4 teams yet. Chelsea was rated as one of the best 4 teams last season and they failed to fulfill that. For now, we don’t need to underate any team until the season starts fully.
If Manchester City are really capable of winning the Premier League title next season, then it will be their 4th title in a row, too good to be true. But I also believe that some Premier League teams will try to stop Manchester City's dominance, even if it's difficult.
Arsenals line up today after they successfully signed Declan Rice from Aston Villa will no doubt be a competent team to dominate the upcoming Premier League season and also a worthy opponent to fight Manchester City from not winning the title for the fourth time in a row.
