Chelsea scored three times in the second period of extra time to hand 10-man Benfica a 4-1 defeat in Charlotte in their weather-affected last 16 Club World Cup clash on Saturday as the English side set up a quarterfinal meeting with Brazil's Palmeiras.
Christopher Nkunku, Pedro Neto and Kiernan Dewsbury-Hall scored in a nine-minute spell to take Enzo Maresca's side through after the teams had been forced off the pitch for almost two hours due to a lightning storm.
Chelsea had taken the lead through Reece James in the 64th minute while Benfica's Gianluca Prestianni was sent off two minutes into injury time.
