Young centre half Brad Beatson took pride from the way in which the Owls’ Under-18s overcame league leaders Charlton on Saturday.
The Middlewood Road clash ended 2-0 to the hosts, who turned in a resolute rearguard display to keep the points.
Beatson said: “It was brilliant, especially against a team like Charlton, who are all big, strong lads.
“It’s not just this match either, over the past few weeks we've been a lot better and a lot more solid at the back and it feels good when you get the win with a clean sheet."
The Under 18s face a trip to Colchester on Saturday and Beatson is confident the team can continue their current run of form.
Wednesday have won three games on the spin as well as posting four successive shutouts.
He added: "We've just got to keep working hard in training every day, and then when it comes to Saturday we'll be ready to go again and grab the win."
