At St James' Park, injury-hit Newcastle were stretched so thin that Eddie Howe had to name three goalkeepers among his substitutes.

But sixth placed Newcastle ignored their fitness issues to bounce back from successive defeats against Bournemouth and Borussia Dortmund.

Newcastle striker Alexander Isak fired home from Lewis Miley's pass to open the scoring in the 13th minute.

Chelsea's Raheem Sterling equalised with a superb free-kick 10 minutes later, but Jamaal Lascelles restored Newcastle's advantage with a header on the hour.

And less than 60 seconds later, Joelinton punished Thiago Silva after the Chelsea defender mis-controlled Cole Palmer's pass.

Chelsea right-back Reece James was sent off for a second booking in the 73rd minute and Newcastle rounded off their demolition 10 minutes later when Anthony Gordon slotted home.

It was the heaviest defeat of Pochettino's first season in charge and the second successive game that Chelsea conceded four goals.
