I've had a good run of counting out Cardiff in home games against both Manchester clubs. On those occasions, City came away with great (a win versus Man City) and good (a draw with Man Utd) results.
The run might end here, though.
The Gunners are top of the league and have a decent away record this season. They're going to be a tough opponent.
The toughest City will face if form is to go by.
I can't see a City win.
