Liverpool will face Chelsea and Arsenal after the victory against Bournemouth, I hope they are not hampered in those two matches because if they are hampered in the end Manchester City will overtake them, there are still several matches that are certainly not easy for Liverpool to get through this season. Therefore, we cannot know how hard Liverpool will maintain their consistency even though Moh Salah will also return to Anfield.
In a long season, it is like a battle and a team win the title by collecting most points compares to other teams. Winning one or two matches or lose some matches, having a first position temporarily won't help to win a title. Liverpool can succeed or fail to defend their first position after next two big matches but even if they fail, they won't lose the Premier League title to Manchester City. The season is still long and Manchester City will have to play against big clubs too.
So far only Manchester City and Liverpool, I also want to inform you that Arsenal is rising from adversity. I hope Arsenal or Chelsea's meeting against Liverpool will not disappoint all Liverpool supporters. I hope they can win the title this season.
Manchester City and Liverpool are most stable in this season and they are far more experienced than Arsenal and Aston Villa in title competition. I believe their experience will help them a lot in this season and also have to count their better quality than Arsenal and Aston Villa.
