Dynamic running from wingers Jadon Sancho and Brahim Diaz in the early periods allowed City to work their opponents across the pitch but it rarely materialised into chances until Dele-Bashiru’s opener on the half-hour mark.
Sancho twisted past right-back Kris Owens before squaring the ball. His cross was turned away but only to Dele-Bashiru, who fired home with his left foot from 18 yards.
Although City could have doubled their lead moments later; it was Liverpool who actually found the net next. A rare foray into the City half saw a cross fall to the feet of Rhian Brewster, who fired into the roof of the net.
The crucial goal did come before the hour mark however as Sadou Diallo met a Phil Foden corner first and headed inside the far post.
City sealed their safe passage with less than 15 minutes remaining as a delightful cross was met by the glancing header of Lukas Nmecha that left Grabara standing.
