Steven Haslam says the Owls youngsters must use Saturday’s late, late loss at the hands of Huddersfield as a learning experience.
Wednesday led 1-0 going into the dying moments at Middlewood Road but were dealt a double blow right at the last to go down 2-1.
Haslam said: “While it was disappointing to lose the game so late on, it’s a learning experience for the boys in managing the game and concentrating right until the final whistle.
“It’s important now that we respond in a positive manner next weekend in another Yorkshire derby at home to Leeds.”
Overall, Haslam reflected on a bittersweet afternoon for the Owls.
He added: "I felt the lads played quite well in the first half without hitting top form but we had a foothold in the game and scored a terrific goal through Mason Duffy, who combined well with George Hirst on his full debut for the Under-18s.
“In the second half we never got going and came under a lot of pressure and finally lost our clean sheet record to a well-struck free kick in the last minute.
“We have to give credit to Huddersfield for the way they pressed us in the second half although I felt we should have shown more bravery to pass the ball as a way of relieving the pressure as well as to create things in the opponents’ half.”
