And the relentlessness with which City have launched their assault on all before them has left the chasing pack gasping for air.
But there will be no time to breathe, as all four take to the field for FA Cup action this weekend in the knowledge that the competition represents their final chance at domestic silverware this season.
Paul Pogba’s Man Utd are first up with a visit to League Two side Yeovil Town, and it seems unlikely that coach Jose Mourinho will rest many key figures following his side’s shock defeat to Bristol City in the EFL Cup earlier this season.
Mourinho treasures every single title his sides can possibly win and will be desperate to see his team progress over a team they’ve defeated in their last three previous FA Cup meetings by a score of 13-0.
Tottenham Hotspur and Harry Kane, meanwhile, face a League Two opponent of their own as they meet Newport County for the first time since consecutive FA Cup meetings in 1959 and 1960.
Spurs won both those games, scoring four goals in each, and will be hoping for a repeat as Kane and coach Mauricio Pochettino continue their search for their first ever major titles in English football.
That, too, will be the task for Liverpool boss Jurgen Klopp, who will be hoping hotshot Mo Salah can fire his side through their all-PL clash with West Brom.
Liverpool are nine games unbeaten against the Baggies in all competitions, and unbeaten in 19 successive games at Anfield.
Chelsea have progressed past Newcastle in five of their last six FA Cup ties, with the Blues winning 1-0 in their most recent encounter in 2006 thanks to John Terry’s goal.
They’ve reached the FA Cup fifth round in 17 of their last 19 seasons and with all their domestic eggs in the FA Cup basket, there will be no room for error.
