Sergio Aguero scored a second hat-trick in three games as Manchester City hammered Chelsea to move back to the top of the Premier League.
Man City were 4-0 up after 25 minutes, with Raheem Sterling slamming home before Aguero smashed in from 30 yards.
Aguero prodded home when Ross Barkley misplaced a header and Ilkay Gundogan struck from 18 yards before the break.
Aguero equalled Alan Shearer’s record of 11 Premier League hat-tricks with a penalty before Sterling’s late strike.
The Argentine – who missed from two yards moments before his eye-catching first goal – also became Manchester City’s all-time leading league goal scorer in the process, moving to 160 goals to surpass Eric Brook on 158.
City now sit top of the Premier League courtesy of a nine-goal superior difference over Liverpool, who have a game in hand.
Chelsea, who had not lost a competitive game so heavily since 1991, are sixth, a point off the Champions League qualification places.
Thomas Partey suspended against Rayo Vallecano
The Ghanaian was shown a yellow card for a foul on Sergio Reguilon in the 62nd minute and this would have also been enough to rule him out of the trip to Vallecas as he entered the derby just one booking away from suspension.
The second yellow for his 80th minute foul on Toni Kroos means that he’ll now be suspended against Rayo Vallecano because of the red card and that he’ll remain one booking away from a further one-match ban when he returns.
Atletico Madrid will visit Rayo Vallecano next Saturday as they try to get their season back on track and they’ll be without Thomas Partey after he was sent off in Saturday’s Madrid derby.
Lucas Hernandez and Antoine Griezmann are both on four yellow cards as well, so will be one booking away from missing the upcoming Villarreal fixture when they play at Rayo next weekend.
