I think he conclude it by analyzing the remaining matches.
I can agree that Liverpool has a higher chance to be the winner because they seem having easier matches.
But Arsenal and Man City look to have the same chance. They still have some big matches, including the match between them (Man City vs Arsenal).
The three teams still have the same chance of winning the EPL title, not just one of them because all three teams also have big matches to play, but Man City still has more matches than Arsenal and Liverpool, namely in the FA Cup so Two teams like Arsenal and Liverpool must make the best use of their time so as not to lose points in every match they face when the Man City players' stamina is drained.
I can give Manchester City more chance compared to the two other teams because based on what we saw from Guardiola and his players in the past, I can say he always has the magic trick and he always has a plan for the last moment of the season.
We can't forget in the last season when Arsenal was in the first place in the table Atreta thought they were going to win the premier league title but Guardiola and his players had better performance time after time when we passed some weeks and this team had a good progress. I think we are going to see the same story and again, Manchester City can have more chances with two other teams, even more chances than Liverpool with Klopp.
