Aguero tied the 11-lap record of the Premier League hat
Sergio Aguero was again the hero of Manchester City's hat-trick, as they returned to the top of the Premier League with a brilliant style by outclassing Chelsea at Etihad Stadium.
Liverpool's victory over Bournemouth meant that Pep Guardiola's team needed the win to get back to the top, even though they had played one more game.
And their work was done after a sensational opening that brought four goals in the first 25 minutes, leaving Chelsea helpless, humiliated and the victim of his worst loss since his 7-0 defeat at Nottingham Forest in April 1991.
The rout started after four minutes when Chelsea was caught by Kevin De Bruyne's free kick, which let Raheem Sterling take it to the last post before Aguero, who had already missed an open goal, completed a magnificent arrival of the right foot. Kepa Arrizabalaga from 25 meters.
Chelsea's embarrassment was symbolized by Ross Barkley's inexplicable header directly at Aguero's feet to poach his second and Ilkay Gundogan completed that early lightning attack with a low shot.
Aguero completed his hat trick from the penalty spot 56 minutes after Cesar Azpilicueta's foul on Sterling, his 15th hat-trick for City and his 11th Premier League record, an honor he shares with Alan Shearer. It was also his second consecutive home game after his hat-trick in the 3-1 win over Arsenal.
Sterling then stacked on agony for Chelsea with the sixth goal, yielding to six yards after David Silva's spun pass released Oleksandr Zinchenko on the left.
Perfect answer from Man City
If Liverpool answered questions with his victory over Bournemouth, City's response here – and over the past week – was even more categorical.
Defending champions Guardiola had a decisive week after their clash with Newcastle United with potentially dangerous home games against Arsenal and Chelsea, as well as a reorganized trip to Everton.
City shone a light on all the dangers, flying over Arsenal and overcoming stubborn Everton before defeating Chelsea with a performance that sometimes reached perfection, especially in the initial phase.
Liverpool still has a game in hand but City has caught up with the essentials of this lost ground and it is a resounding message that he will not be handed the title.
Chelsea, one of the teams to conquer City this season, was sacked with a minimum of complications and the momentum that City seemed to have lost on Tyneside is back in the most frantic way.
And, in the market, they gave a huge boost to what can still be a decisive equation for goal difference.
Sarri Ball becomes sorry ball
Aguero scored his second goal at home after Ross Barkley put the ball back in his own penalty area
If Maurizio Sarri thought his lowest point had been reached with capitulation in the second half in the 4-0 defeat at Bournemouth, Chelsea boss now has to revise his opinion.
Chelsea may not have been the rival of the title with City all season, but it was a poignant illustration of the current gap between the two camps, which bothered the Italian public.
Sarri's approach has not allowed Chelsea to move forward in recent weeks and his concern is that his owner, Roman Abramovich, will not appreciate the look of this performance or the margin of defeat – and perhaps more so the makes them sixth and may not make the first four qualifiers of the Champions League.
Chelsea's performance was characterized by defensive disorder, complete extinction for first goal and the head of the unfortunate Barkley directly to Aguero for City's third goal.
N & # 39; Golo Kante is wasted away only as the best midfielder in the world while Jorginho (who ended up choosing Chelsea rather than City) is a player whose influence diminishes each week.
Eden Hazard was indefatigable and Gonzalo Higuain was ready to shoot at sight – but they were terribly served at a performance in Chelsea that was a complete disaster.
A mess that will greatly worry Sarri and Abramovich.
