Liverpool leapfrogged Manchester City at the top of the table after beating Fulham 2-1 at Craven Cottage.
The champions were in FA Cup action so have a game in hand, while Chelsea suffered a blow in their top four hopes with a defeat at Everton.
Here, AMITAI WINEHOUSE assesses 10 things we learned from the latest round of Premier League fixtures...
Graeme Souness’ Eden Hazard warning was rightGraeme Souness pointed out after Chelsea’s loss at Everton that if you shut down Eden Hazard, Maurizio Sarri’s side have very little about them.
That bore out at Goodison Park — a ground Hazard has failed to score at in all seven of his Premier League appearances there. Keeping up that habit led to more dropped points for Sarri’s boys.
Many Chelsea managers have relied on the Belgian but few had the supposed philosophy of the Italian. Souness is right - it is now clear that Hazard has carried Chelsea this season.

There has been talk of Liverpool’s front three misfiring, that they are not linking up well anymore. Fulham showed that at least two are working right.
After his cross for Sadio Mane on Sunday, Roberto Firmino’s last seven Premier League assists have been for either Mohamed Salah or Mane, which shows they still have that brilliant understanding.

But Salah, on a personal level, is clearly struggling and he is going about solving it in completely the wrong way.
He is clearly desperate to end a run of seven games without a goal but there are ways to go about that. Taking five shots - most of which were from range - and providing no chances for his team-mates is not the correct one.
The Egyptian is playing too individualistically. He needs to be reminded that team success is more important than his own. That will come with time.

David de Gea did not have the best of times against Arsenal but his importance to Manchester United was highlighted in the Wolves game.
United can lay claim to the best backup goalkeeper in England but Sergio Romero remains just that — backup. De Gea would probably have saved both of Wolves’ goals with those ultra-talented legs.
Romero cannot be put at fault yet this is a lesson for Ole Gunnar Solskjaer. With Real Madrid chasing him, De Gea is priceless if United want silverware.

Time to worry, Liverpool. Manchester City have a habit of being overwhelmed when they fall
