Jose Mourinho refused to come out and speak for his post-game press conference but, on this occasion, he wouldn't have been able to spin it or downplay it: Chelsea have a huge say in this title race.
Yesterday against a 10-man Swansea they took an appreciable step. That was thanks to Demba Ba making a significant leap. Although this was the striker's first start since October, he ended up providing the finish Chelsea so badly needed.
It is quite a resurgence, especially after the heroics against Paris Saint-Germain, and Mourinho's side must now keep that momentum going.
In truth, though, this game illustrated why his side had recently lost the Premier League lead.
Despite Chico Flores' 18th-minute red card after a long deliberation by referee Phil Dowd, Chelsea made hard work of opening Swansea up.
