Kevin Nugent has praised his Under 23 side after our young Lions overcame Nottingham Forest at a scorching Calmont Road by a 2-0 scoreline.
Harvey Bradbury and George Alexander (pen) netted in each half to seal the three points, and Nugent has lauded the application of his youthful side.
"I thought it was a really competitive game in blistering heat," the U23 manager says.
"The lads put in a real shift to get that 2-0 win. The endurance needed during the game will certainly benefit the boys - it would have been tough for both sides.
"We got a goal early on with Harvey and then had to hang on against a good footballing side. Later on we countered more, and won the penalty which George stepped up and scored. It's a learning curve, and there are certainly things to improve on, but the spirit and application were fantastic."
Nugent gives a notable mention to the way the team defended and ground out a clean sheet in the victory, and claims it is something encouraging to build upon.
"It's always pleasing defensively to keep a clean sheet, because we do a lot of work on the units in midfield and at the back.
"Joe [Wright] did excellently in goal - he had to come out and very bravely take a smash in the face to stop a Forest opportunity.
"So I was really pleased on the defensive side. If we can keep clean sheets that's great, and then we have some flair players in the team who can create chances for us."
Opponents Forest enjoyed a 100% record in the Professional Development League until facing Millwall - which Nugent is delighted with - and the U23 boss gives credit to Jimmy Gilligan's East Midlands side.
"Forest are a really good side with some brilliant players in there. We've seen a couple of their previous games, and they're always developing players, with a big catchment area. They're a massive club with a very good coach in Jimmy.
"So that was a real tough challenge for us today, and we're really pleased to have come out on top. The start to the season has been encouraging and pretty solid.
"We have a real spirit within the group, there's no doubt about that. Unfortunately against a strong Leeds side we just let that one slip late on, but we look at every game and focus on what to improve and build on, individually and collectively. That's what you expect with a development side. I'm pleased with the start, and that was a very good win."
