The Manchester derby will provide Manchester City with another barometer of where they are in their ambitious project.
They passed their first major test of the season last Saturday as they defeated Arsenal 4-2 at Eastlands. Mark Hughes has spent millions in the transfer market and his side flexed their muscles to devastating effect against the Gunners.
But this trip to Old Trafford is sure to put their 100 per cent start to the season in jeopardy as they face a United team who produced their best performance of the season in beating Tottenham Hotspur 3-1 last weekend.
