City created a host of chances in a completely dominant first-half display and led 3-0 at the break through strikes from Phil Foden, Jack Grealish and Kevin De Bruyne.
The onslaught continued after the break and Riyad Mahrez bagged City's fourth before De Bruyne rifled home a rocket to bring up the nap hand.
Despite a tremendous double save from Illan Meslier, John Stones then made it 6-0 with 16 minutes left and Nathan Ake headed home City's seventh just four minutes later.
