As a group we've got to learn very quickly that we can't keep conceding goals and making silly errors because it costs the teamPaul Robinson.
The visitors scored four times without reply before substitute Amari Miller netted a late goal for the hosts with just minutes of the game remaining.
Despite making a decent start, Blues found themselves behind after just 18 minutes when Chris Conn-Clarke opened his account.
The same player added a second just before the break, before completing his hat-trick in the 55th minute.
The result was then put beyond doubt with 77 minutes on the clock as Mitch George fired home a fourth for the Clarets from close range.
Miller's 84th minute finish was little more than scant consolation for Blues.
Blues' Lead Professional Development Coach Paul Robinson admitted his players fell well below the standards he expects of them and insists they are capable of much more.
"My overall assessment was we were poor," he admitted.
"Burnley won every battle and they were better than us and from the word go they were the only team that wanted to win the game.
"As a group we've got to learn very quickly that we can't keep conceding goals and making silly errors because it costs the team.
"When you're having to chase the game, you're then losing by more because you're opening yourselves up.”
"We'd actually started really well in the first 10 minutes as well," continued Robbo.
"We’d put the ball down the sides a few times to get in and had chances, but again it was poor decision making.
"We've got to be more compact and streetwise about positions on the football pitch and making the right decisions as well.
"But fair play to Burnley, they knew what they were doing, and they just kept the ball.
"They had two very exciting wingers who are second year scholars that have been out on loan playing men's football and have come back and are better players for it.
"We're still young, with the majority of players still first years, but this what football is like and they have to get used to the physicality and teams being in their face and it's how they deal with it."
Moving forwards, Robbo expects his youngsters to start taking more individual responsibility during games.
"They need to understand I can't be on the football pitch with them,” he said. “I can give them all the tools and all the training sessions that they want so that they go into a game properly prepared, but when they cross that white line, they've got to do it.
"I know the quality and ability they've got, but quality doesn't sometimes win you games and you've got to fight your way into games.
"I enjoy working with them and they're a good group, but they really need to start watching football matches and understanding the game better and how they can go on to be better football players.
"We need to be a team, both defensively and offensively, we can't just be individuals."
