In a season of bonkers matches between the big guns, this ranks as the craziest. Arsenal started the game top of the league with the best defensive record, having shipped just 11 goals in their first 15 matches.

Sergio Aguero volleyed City into an early lead before Theo Walcott equalised.

City retook the lead through Alvaro Negredo, and with Gunners defender Laurent Koscielny hobbling off the visitors looked less stable at the back.

Fernandinho swept home a third before Walcott pulled one back, but David Silva made it 4-2 just minutes later.

A frantic end saw Fernandinho slot in a fifth for City, Per Mertesacker head in Arsenal’s third and Yaya Toure tuck in an injury-time penalty.

Utter madness.
