Chelsea’s Senegal striker Nicolas Jackson diverted a Palmer shot past goalkeeper Martin Dubravka in the sixth minute before Newcastle battled back to equalise in the 43rd when Alexander Isak curled a shot beyond the dive of Djordje Petrovic.
Chelsea, urged on by their fans after some had turned on Pochettino and the club’s US owners in a 2-2 draw at Brentford nine days ago, restored their lead in the 57th when Palmer, the Blues’ top scorer this season, scored from outside the box.
Substitute Mykhailo Mudryk made it 3-1 in the 76th minute when the Ukrainian danced through Newcastle’s defence, rounded Dubravka and slotted home. A fierce shot by Jacob Murphy gave the visitors hope in the 90th minute but Chelsea held on.
