An 83rd-minute Weverton own goal from a deflected Malo Gusto cross gave Chelsea a nervy 2-1 win over a spirited Palmeiras side in the Club World Cup quarter-finals on Friday.
Chelsea made most of the running and dominated early on but were reckless with their finishing and went into the break with a one-goal advantage thanks to Cole Palmer's 16th-minute strike.
Palmeiras roared back after halftime with teenage winger Estevao, who is soon to join Chelsea, equalising in the 53rd minute with a stunning strike from a tight angle.
Seven minutes from time, Gusto's attempted cross deflected off defender Bruno Fuchs and wrongfooted Weverton, the ball bouncing off his back and into the back of the net.
Chelsea will now face another Brazilian side in Fluminense in the semi-finals in New York on Tuesday.
Substitute Hercules scored his second goal in as many second-half appearances to lift Fluminense into the semifinals with a 2-1 quarterfinal win over Al Hilal in Orlando.
Martinelli also scored late in the first half to continue a fabulous tournament for the Rio de Janeiro club and Brazil overall. Palmeiras also got to the quarterfinals before falling 2-1 on Friday to Chelsea, who will oppose Fluminense on Tuesday in a semifinal match at East Rutherford, N.J.
Al Hilal exits despite a fourth tournament goal for striker Marcos Leonardo, who was in for the injured Aleksandar Mitrovic.
The Saudi side was the last from Asia remaining, having pulled off the tournament's biggest upset with a 4-3, extra-time victory over Manchester City in the second round on Monday.
