LONDON — Just three months into the season, it is hard to see how Chelsea can be stopped in its remorseless charge to the English Premier League title.
For many, the biggest question now is whether it can go through the season unbeaten.
Chelsea got past another major obstacle on its way to the league title by winning, 2-1, at Liverpool on Saturday and running its record to nine wins and two draws.
Defending champion Manchester City, probably Chelsea's biggest rival, is eight points behind in third after 11 games following a 2-2 draw at Queens Park Rangers.
Chelsea came from behind to beat Liverpool at Anfield in the Premier League, with Diego Costa scoring the winner in the 67th minute.
Emre Can put Liverpool ahead in the ninth minute with a long-range strike that deflected off Gary Cahill, before Cahill reacted quickest in a goalmouth scramble to equalize with a 14th-minute goal that needed confirming through goal-line technology.
Asked if his team could go through the season unbeaten, Mourinho said it would be "the impossible job." Yet Chelsea has played four of its hardest away matches this season — the two Manchester clubs, Liverpool and Everton — and is even harder to beat at home.
Southampton stayed four points behind in second place thanks to Shane Long's double in a 2-0 win over Leicester but Man City dropped two more points by drawing at QPR, with Sergio Aguero scoring two equalizers to take his league-high haul to 12 goals.
Manchester United won, 1-0, against Crystal Palace thanks to a goal from Juan Mata. Burnley won for first time this season, 1-0, against Hull, and West Ham played to scoreless draw with Aston Villa.
