MAN City hammered Arsenal to make it 18 successful League Cup ties in a row and pile the pressure on Mikel Arteta.
Gabriel Jesus headed home after just two minutes before Alexandre Lacazette headed home an equaliser.
But things went wrong for the Gunners when Gabriel Martinelli went off injured early in the second half.
A howler from goalkeeper Runar Alex Runarsson saw Man City take the lead from a Riyad Mahrez free kick.
And Phil Foden and Aymeric Laporte then made the game safe.
