Newcastle were set up to frustrate - ceding possession and piling men behind the ball - but Hazard was a constant threat, capping a man-of-the-match display by dispatching Chelsea's controversial penalty.
The Italian worldwide is far from a goalscoring midfielder but we've already seen that he's pretty brilliant at taking penalties after his sublime spot-kick on his Premier League debut.
However, he says that a team taking time to adapt is nothing new in his experience, and he is sure his players will come round to it sooner rather than later. "It was a good win and the three points are massive for us".

It is not the first time Benitez has been on the receiving end of barbed attacks from the television studio as Sky pundits Graeme Souness and Jamie Redknapp delivered a stinging appraisal of the display.
"If you are used to defending by looking at the man, and I ask you to defend by looking only at the ball, if you are 18 it's maybe easier. It's usually three months, but my feeling is in this team there are a lot of intelligent players so I hope only two months", he said.
"I have to say thank you to Rafa because when I arrived in Naples I had a feeling the team was nearly ready to play my football", he said.
With this victory, Chelsea made it 9 points from 3 matches and Sarri has begun his life as Chelsea's gaffer on a positive note. The headline statistic is that Hazard has contributed a goal and two assists in just 133 minutes of Premier League action this season, but a deeper look at the numbers throws up more cause for encouragement. "We are only three games in". "It is easier, for a defender who is 30, it is more hard".
Should we let Cahill leave, Chelsea would only have Andreas Christensen, David Luiz and Antonio Rudiger as centre-backs with first-team experience.
