Having already beaten Leicester twice this season, including victory in the Carabao Cup, the holders were favourites to progress, though they fell behind shortly before half-time when Bobby De Cordova-Reid reacted quickest to Wilfred Ndidi’s shot being saved by Onana to head the ball over the Man Utd goalkeeper and into the back of the net.

This will mark Leicester's third visit to Old Trafford this season, having suffered heavy losses in both the Carabao Cup and Premier League, conceding eight goals.
