The Senior Professional Development Phase Coach’s side hit the Bantams with a four-goal second half salvo to claim victory in the second group game of the Final Third Development League Cup.
And Jolley felt the side’s philosophies helped the youngsters to a vital win, as they look to reach the knock-out phase.
He said: “I thought we were excellent in the second half, but also in the first half too. It was a tight game and they were decent, causing us a couple of problems and I just said to the players it’s all about relying on good basics to make sure the fundamentals and the framework of the team are there.
“We know we aren’t going to play well all the time, for the full 90 minutes, but in the second half our good attacking play came to the fore and we scored four good goals, so I am delighted.”
Jolley was forced to make drastic changes to the back four, after loan spells and injuries resulted in midfielders Steven Hewitt and then Bradley Jackson filling in at right back, before midfielder Brandon Wilson played the remaining half an hour at centre back, replacing the injured Alex Whitmore (below).
The former Crewe coach said: “We have had to mix and match a little bit because Luke Hendrie has gone on loan, as have Luke Conlan and Cameron Dummigan.
“Alex had to go off through injury and Tom Anderson travelled to Nottingham (Forest) with the first team, so it’s tough constantly trying to put a back four together. But the lads that have gone in there did extremely well and it’s a good experience for them to sometimes play out of position.”
The Development Squad now have four points from two games in the group stage with one game to play against Morecambe in November.
And after following up their first game draw with Fleetwood Town, Jolley believes thinks the Clarets need another win to progress.
He explained: “The game was all about getting another good performance and a win ideally and we have done that.
“Of course. we would like to go through and go as far as we can in this competition, so we’ll look and see what the scenario is and see what we need to do against Morecambe.”
There were more positives from the game, as first team defender defender Kevin Long completed another 90 minutes as he nears his comeback from a knee injury sustained at Newcastle on New Year’s Day.
Jolley added: “Longy has had a few games back now and each game he looks sharper and stronger.
“Each game he gets closer to that genuine match sharpness, so I am really pleased and I thought he was excellent.
“He was the captain of the team and he led them really well, so I was delighted with him.”
Youth Team striker Khius Metz (below) also grabbed his first goals for the Development Squad, scoring a brace after he was introduced with 20 minutes to play.
Jolley said: “Khius is a player we have got a lot of interest in because he has got such good pace, so he can threaten teams in behind.
“I spoke to him after the game and told him if he can improve his football and keep working hard at his game then he is certainly a player that we want to continue working with.”
Jolley also expressed his delight at versatile defender Hendrie making his first loan move, and also earning a clean sheet in what was his Football League debut.
He said: “I spoke to the people at Hartlepool after the game and they were delighted with Luke and I’m not surprised.
“He is a great lad with a super attitude and he’s been doing really well for us, so I’m not surprised somebody has taken a chance on him and I am sure he won’t let them down.”
