It was the night when the fire surely went out on Arsenal's previously explosive Premier League title challenge.
Inspired by Kevin de Bruyne, Manchester City were truly dominant as they routed their rivals 4-1 at the Etihad, with the Belgian playmaker setting the tone with a sublime finish 12 minutes in. John Stones headed a second before the break before de Bruyne added his second early in the second half - and Rob Holding's late consolation couldn't mask the gulf in class as Erling Haaland then got the goal he deserved in injury time.
Of course, Arsenal remain top, but that position now looks beyond precarious. Mikel Arteta's men are on 75 points after 33 games with City on 73 having only played 31. It's not quite impossible, but The Gunners are now relying on Pep Guardiola's men slipping up at least twice.
