Manchester United needed extra-time to book a spot in the FA Cup semi-finals after defeating Norwich City 2-1 on Saturday evening.
David De Gea dropped to the bench in favour of Sergio Romero, while there were also starts for Odion Igalo, Jesse Lingard, Fred and Juan Mata.
Bruno Fernandes, who starred in the last two matches, looked to sprung United to life with earlier movements in and around the danger area but the Canaries proved tough to crack.
Harry Maguire put his body on the line to deny Tim Cantwell giving the hosts the lead from the far post area in a half of little to no clear-cut chances at all.
Both sides started the second half with no changes off the bench, as a looping ball from the far side by Fred nearly led Ighalo through but a defensive intervention came to the fore.
Ighalo wasn’t to be denied again after a low cross from Luke Shaw came off Juan Mata before reaching Ighalo who stayed onside to dink beyond Krul five minutes from resumption.
The Red Devils decided to go with a refreshed approached within ten minutes, with Marcus Rashford, Mason Greenwood and Paul Pogba entering among others.
Cantwell brought the Canaries level in the final 15 minutes after his long range drive from outside the area nestled the bottom corner.
Norwich were down to ten players two minutes from time with Timm Klose, given a straight red for a foul on Ighalo as Krul denied Pogba from close range to send the match to extra time.
United reclaimed the lead with three minutes remaining in extra time after Maguire slammed home a loose ball from close-range, helping his side into the semi-finals.
