MANAGER Peter Jackson described the performance of Town's teenage centre-backs as "unbelievable."
Jackson switched formation to accommodate Nathan Clarke's suspension and had Tom Clarke (17) and David Mirfin (19) at the heart of a flat back four.
"Those two lads were unbelievable," enthused Jackson after only a second derby win in nine attempts this season.
"You won't see a better performance at the back than that from any two young centre-backs outside the Premiership.
"All the young lads were outstanding, though, and some of the older ones weren't bad either!
"It was a really good team performance and, when we play like that, we are very hard to overcome.
"The second successive clean sheet is really pleasing for everyone concerned.
"Clean sheets win you play-offs, automatic promotion and championships and if we start keeping more, we will definitely go on and do something."
Jackson reported no injuries as he prepares for Saturday's trip to Peterborough.
"The tackles were flying in, but you've got to expect that in a local derby and we never shirked one of them, which makes me really proud," added the manager.
"I felt we dominated in the first half, should have been more than one goal to the good and, even though we came under a bit of pressure at times in the second half, I always felt comfortable because of the way we were defending as a team.
"The lads have put a lot into these last few games and to win three on the trot is great."
