there is still a match to be played. and if City is not consistent then they can of course slip. because there are Liverpool and Chelsea who are ready to take a position.
Liverpool and Chelsea's opportunities are still big open. but it depends on their ability to get full points. because City also seems to only take it safely to keep getting points in every game. they are no longer productive with many goals, like the games at the end of last year.
if it does slip, I might see Liverpool as champions.
