Everything you wrote could be said about Man City or Arsenal... Now they have roughly the same opportunities to top the standings... Based on last season's experience, Man City are probably the most stable of these clubs... Last season they easily moved Arsenal away... Perhaps this time they will repeat it with Liverpool...
I agree with you that Manchester City is the most stable club in the Premier League when it comes to winning the Premier League title in the past six years. That does not mean it is certain that Manchester City will win the title this season. I think Arsenal might end up winning the Premier League title this season because they are in great form and scoring a lot of goals against their opponents.
It's anything but certain that Manchester City wins the Premier League title this season. Apart from the fact that Arsenal is now super stable again and that their results are impressive, I think that the win of the final against Chelsea in the League Cup may have been the kick-off to something big for Liverpool and Klopp. Those guys are hungry for titles and they got started with the first trophy. I am absolutely sure that they will play at their damn maximum level until the end of the season. They scored Liverpool 11 goals in their last 3 Premier League games and they are set to keep going like that. See how they played the final without so many superstars of which some will return quite soon. They can only get better from here and their motivation couldn't be any higher than that. In my opinion they are the hottest title favorite.
