An Eddie Nketiah double saw Arsenal book their place in the quarter-finals of the Carabao Cup on Tuesday.
The 18-year-old came on with just five minutes of the game left to play, and with the Gunners 1-0 behind.
Josh Murphy had given the Canaries the lead with a first-half strike, but a Nketiah toe-poke from a corner took the game to extra time.
The teenager then bagged a header past Angus Gunn to book Arsenal's place in the quarter-finals of the competition.
Here's how our man Adrian Kajumba rated the performances from the Emirates.
ARSENAL
Macey 8
Was exposed for goal but helped keep Arsenal in tie with saves from Oliveira and Murphy.
Debuchy 5
Played scorer Murphy onside and didn't have pace to catch him.
Elneny 5
Lucky to escape a red for bringing down Oliveira as last man.
Holding 6
Wasn't overworked and went close to scoring with first-half header.
Nelson 7
Pushed back by Murphy but positive every time he went forward.
Coquelin BOOKED 5
Made little impact on the game other than being booked for rash foul.
Wilshere BOOKED 6
Back in central midfield. Has looked better further forward this season.
Maitland-Niles 5
Passed up two good opportunities to shoot when he chose to pass instead.
Walcott 5
Captain for the night but failed to lead by example.
Iwobi 5
Was robbed of possession just before the goal. Not his night.
Giroud 5
Another ineffective display, this time not rescued by a wonder goal.
