Pedro and Willian's goals gave Chelsea a tough 2-1 victory over Newcastle, which opened a six-point gap to Arsenal in fifth place in the battle for a place in the Champions League.
Despite an impressive performance in the week-long loss to Tottenham in the Carabao Cup semi-final, Chelsea Maurizio Sarri opted to leave Bayern Munich goalkeeper Callum Hudson-Odoi on the bench.
And it was his replacement Pedro who opened the scoring in 10 minutes. The former Barcelona player picked up David Luiz's exquisite ball and kept his composure to delicately lift the ball over Newcastle goalkeeper Martin Dubravka.
The goal set the tone of the game, as Chelsea dominated possession and appeared only a matter of time before they scored their second.
However, they recovered in 40 minutes, as Newcastle took advantage of a good spell to make the 1-1 with Ciaran Clark heading home from a corner.
The goal encouraged Newcastle and they finished half at the top, with Chelsea struggling to knock them down, and there were even audible boos from the home crowd when Jorginho played the ball directly out of the game early in the second period.
But Chelsea again took the lead in 56 minutes through a sensational effort from Willian. The Brazilian international received the ball Eden Hazard and cut from the left before pushing an effort into the back of the net from the edge of the box.
Hudson-Odoi then replaced Pedro in the final minutes to make his second appearance in the Premier League of the season and received a warm welcome from local fans.
The result leaves Chelsea only one point behind third place Tottenham, who has a game in play, while Newcastle will end the weekend in the relegation zone.
