MANCHESTER, England (AP) – Chelsea suffered its biggest defeat in 28 years on Sunday, when Manchester City beat Maurizio Sarri's team 6-0 in the Premier League.

The meeting of the last two champions was a total imbalance as Sergio Aguero managed a hat trick for the second consecutive weekend.

City regained Liverpool's lead in the title defense as 2017 champion Chelsea finished the weekend finishing sixth.

Raheem Sterling scored two goals – City's first match in the fourth and sixth in the 80th minute – and Ilkay Gundogan also scored.

This is Chelsea's third consecutive loss in the league, following a 2-0 defeat at Arsenal and a 4-0 humiliation against Bournemouth.

And Sarri, who finishes his first season as a manager, is now far from acquired.

"I do not know, you have to ask the club," said Sarri, who was hired after leaving Napoli. "I'm worried about my team, I'm worried about the performance, but my job is still under threat, so I'm not worried about the club. You must ask the club.

"I did not see my football (against City). At the beginning (of the season) it worked. Now all we have to do is understand why it's not working right now … It's not easy. At first, we played better than at home. Now we play better at home than outdoors.

Chelsea had not lost six goals or more since April 1991 – a year before the start of the Premier League – when Nottingham Forest had beaten the West London club 7-0.

Chelsea was not chosen after just four minutes at Etihad Stadium. Kevin De Bruyne was released by Bernardo Silva on a smart shot shot right.

"I think we started well, then we conceded the goal after four minutes stupidly," said Sarri. "At that point, we had to stay in the game and we could not do it because we had made a lot of mistakes against the bad guys."

The match also saw an error from Aguero.

Aguero should have doubled in advance almost immediately, but remarkably missed closely. Silva had crisscrossed the area to create an opportunity at the verge of gilding, but Argentina's striker stood out in unusual ways.

The director Pep Guardiola dropped to his knees, frustrated, but he soon rejoiced to see Aguero forgive in a sensational way. The striker played a 1-2 with Oleksandr Zinchenko out of the box, then fired a powerful shot that flew 25 meters in the 13th minute.

"From scratch," said Sterling, "he can put the ball in the top corner and players like that, you have to cherish them."

The second of Aguero was offered to him six minutes later. David Luiz was heading well ahead, but Ross Barkley was inexplicably heading for the danger zone. Aguero was hiding in the penalty box and punishing the former Everton midfielder from a tight bend.

Chelsea barely had time to take stock before the visitors concede again. Gundogan scored in 25th place with a nice shot from the edge after a slight clearance from Antonio Rudiger.

City was released for the remainder of the first half and Chelsea striker Gonzalo Higuain even managed to test goalkeeper Ederson with a clean volley.

Although Aguero went against the crossbar at the start of the second half, he had only to wait for the 56th to seal his 15th round of the City hat and his 11th record in Premier League with Alan Shearer. Sterling was brought into the area by Cesar Azpilicueta and Aguero stepped up and sent Kepa Arrizabalaga the wrong way from the spot.

City seemed to leave nothing to chance with De Bruyne taking a free-kick on Arrizabalaga and Aguero pulling in the side net.

Sterling finished his brilliant afternoon of work after his replacement, David Silva, opened the Chelsea defense again and Zinchenko picked the striker for a close-up shot.

"Something is changing," said Sarri. "At the moment, I'm not able to understand the reason, but I have to work because my goal is to play football, not to change football, because at the moment we are playing another one."
