The bookies now see the title race as a straight fight between Chelsea and Manchester City and it's hard to disagree.
Yes Liverpool are in irresistible form but you feel one injury to a star player could destabilise them: this might be one season too soon.
And while Arsenal - at 20/1 - are a crazy price, punters just don't trust them when the going gets tough.
Chelsea deserve to be favourites; City have games in hand but Jose Mourinho's men have points on the board and a run-in any of their title rivals would envy.
After Spurs on Saturday, seven of Chelsea's last nine games are against teams in the bottom half; and six of those are against teams in the bottom seven!
Of their rivals they face Arsenal at home in a fortnight and then must go to Anfield at the end of April when who knows it could be winner takes all!
But Chelsea have been here before; they have a focus and intensity about their play if not the fluency that would please neutral observers.
Mourinho has gone back to basics: keep a clean sheet, nick a goal, worry about the result not the performance.
They've conceded five goals in their last 13 games - none of which they've lost and ten of which they've won.
And it's that run of form which has seen them leap from the pack to the head of the race.
It's not really the aesthetic style Roman Abramovich had in mind when collecting so many skilled footballers but it's winning football, and if the title is within your reach why not grasp it?
It looks like mission impossible then for London rivals Tottenham on Saturday Night Football but don't forget Spurs boast the best away record in the Premier League.
It's just that they have never won a Premier League game at Stamford Bridge and their failure to beat any of the top four clubs this season suggests they're not about to start now.
But Tottenham are still clinging to a Champions League dream which would inch closer to reality if they could become the first side to inflict a home league defeat upon Mourinho's Chelsea.
