Super Eagles forward Victor Moses did not feature for Chelsea as he was an unused substitute.
Two first half goals from Michy Batshuayi and a brilliant free-kick by Marcos Alonso secured the impressive win for the Premier League champions.
Chelsea had the game’s first real chance on 17 minutes after they were awarded a free-kick on the edge of Newcastle 18 after Chancel Mbemba fouled Eden Hazard but the Belgian’s effort came off the defensive wall.
Newcastle went very close to broking the deadlock on 25 minutes only for Jonjo Shelvey’s left-foot strike to be superbly saved by Willy Caballero at the near post following a good cross from Massadio Haidara.
Chelsea eventually took the lead in the 31st minute through Batshuayi who tapped in from close range off Alonso’s assist.
Dwight Gayle had a chance for Newcastle in the 36th minute after wriggling away from Antonio Rudiger but his low left-foot shot was saved by Caballero.
Shelvey should have level matters for Newcastle on 43 minutes following poor defensive play by the Chelsea defence but Caballero got down well to make the save.
At the other end, Chelsea doubled their lead through Batshuayi again in the 44th minute as his low shot off a pass from Hazard was deflected into the net by Jamaal Lascelles.
In first half added time, Caballero produced two big saves, first palming away Shelvey’s deflected low strike before punching away Mbemba’s goal bound strike.
Chelsea went close again on 56 minutes following a brilliant left-foot volley by Alonso from Davide Zappacosta’s cross but Karl Darlow produced a superb save to deny the Spaniard.
Alonso made it 3-0 in the 72nd minute with a brilliant free-kick over the Newcastle wall after Zappacosta was fouled close to box.
Pedro should have extended their lead on 80 minutes after Ethan Ampadu picked out the Spanish forward but Darlow got off his line quickly to clear the danger.
A minute later, Darlow was called to action again as he tipped Zappacosta’s left-foot strike over the bar.
Batshuayi should have completed his hat-trick on 88 minutes after beating his marker but his shot from range was well blocked by Darlow.
In first minute in added time, Batshuayi had another chance but once again Darlow thwarted his shot from a tight angle.
