Manchester City's resurgence in the Premier League came to a screeching halt on Sunday as they lost 5-1 at Arsenal.
The match was blown wide open by the Gunners in the second half, as the home side scored four straight goals put the result beyond doubt.
It was a much more even affair prior to Arsenal's goal explosion, with Erling Haaland equalising early in the second half only to see the hosts permanently regain the lead just a minute later.

For Man City defender John Stones, who had a better view of the Arsenal onslaught than almost anyone else, Sunday's match was a tough one to take after the club went undefeated in the previous six league games to climb back into the top four.
"It is difficult,' Stones told Sky Sports. "I think all of us don't take losing well.
"It is hard to put into words straight after a game like that. Pride hurts. Sorry to the fans that have traveled to come and watch that.
"How we played in the last 30 minutes was not acceptable. Personally and collectively, it's not us.
"It is not nice to be involved in that when you know it's not your team in those situations. Credit to Arsenal, this is not an easy place to come to. For 65 minutes, we played some great football at times.
"We were in the game and it was a swinging point. It swung the wrong way for us. I am angry, upset personally and collectively about how the game finished."
Stones admitted some fault on Thomas Partey's 56th-minute strike that swung the momentum back into Arsenal's favour, as the ball struck him and deflected past goalkeeper Stefan Ortega for the game's decisive goal.
However, the 30-year-old believes the entire Man City team were guilty of not playing up to their potential.
It's something that Stone struggles to understand.
"We stopped doing the things we meant to," he said. "Difficult for me to put into words.
"A lot of different things that I have not figured out why we are not picking up results.
"The passion is there, the training and everyone has the right intention.
"We have not got to where we are without difficult times and that is through everyone's career right now.
"We all have to stick together, that's a key point that we don't start to point fingers."
