Norwich City Under-18s made it five games unbeaten with a 4-1 win away to Arsenal in the Under-18 Premier League South.
Norwich went ahead after 13 minutes through Kahlil Steele, who fired in at the Sobha Realty Training Centre.
And the Canaries doubled their lead 10 minutes before half-time, as Reuben Cooper found the back of the net.
In the second half, Cooper added his second, and Norwich's third, scoring from close range after being found by Mundle.
Four minutes from time, Mundle got himself on the scoresheet as he added a fourth goal for the Canaries.
There would be no clean sheet, however, as Brando Bailey-Joseph scored in the third minute of injury time for Arsenal.
