Chelsea manager Frank Lampard, speaking to BBC Match of the Day: "We dominated every aspect of the game.
"They hit the bar in the first half but the rest of the game was ours, except scoring.
"Newcastle defend their box, you won't make too many clear-cut chances against them. We controlled the game, we were at the end of their box. If we want to go to the next level we have to take chances and score in these kind of games.
"The lads have got their heads down in there. But the brutal reality of football is if you don't score, teams stay in the game and something like that happens at the end."
Newcastle travel to Everton in their next game on Tuesday, 21 January (kick-off 19:30 GMT), while Chelsea host Arsenal in the evening's late kick-off (20:15 GMT).
