A Federico Fernandez own goal and a second-half strike from Tammy Abraham helped Chelsea to a comfortable win at St James’ Park.
The victory saw Chelsea go top of the Premier League table but it should have been far more comprehensive as they missed several goalscoring opportunities against a disappointing Magpies side.
Timo Werner and Abraham were both denied by two early good saves from Karl Darlow before Fernandez diverted a Mason Mount cross into his own net after 10 minutes as the Blues came racing out of the blocks.
Werner then fired wide with just Darlow to beat just before halftime before spurning another glorious opportunity 10 minutes into the second period.
The German striker dispossessed Fabian Scher on the edge of the Newcastle box, but opted to pass instead of shoot and the ball was hacked clear.
But the former RB Leipzig man showed all of his quality to set up Abraham for Chelsea’s second when he picked the ball up deep in the Newcastle half, left several black and white shirts in his wake before teeing up Abraham who fired home off the inside of the post.
Werner did have the ball in the net just before being substituted but the effort was ruled out for a marginal offside.
Newcastle offered little in attack with Sean Longstaff effort that crashed off the bar in the second-half the nearest the Magpies came to scoring.
