If I'm not wrong Manchester City can take the lead from Liverpool if they manage to win their missing game. Manchester City will probably win that game which is Brentford as well. But until then they have to keep the point gap like this at worst. Maybe they can get ahead earlier as well in Salah's absence for Liverpool but we will see.
In short Liverpool must be fully aware of the big threat behind. In the meantime I'm curious about Arsenal too. Do you think they can rejoin the title competition? I really can't be sure of them because of the highly inconsistencies they have every season.

I don't see Arsenal playing to win the league title. They really started well at the beginning of the season but now they playing is just inconsistent. Although the league title is still much open but it mainly between Man city and Liverpool. Although alot of matches are still to be played, so no one can really say who the league title belongs to.
