Sol Campbell says the last few weeks were a learning curve for the squad.
Blues have not won in their last four games but have gone into half-time in each of their last three with the score 0-0.
There have been 10 first team debuts from Academy players throughout this season and Campbell says it’s a about learning and growing from these experiences.
“For us it’s a big learning curve,” he said. “It’s been pretty tough having all the Academy players we’re trying out.
“It’s been a process finding which players can fit in and last. It’s been a nice way of doing things, but it hasn’t always worked.
“We’ve got a few guys in there who can go again and that’s the main thing, go again. It’s all about recovering to go again.
Campbell added: “It’s a learning curve for me too, having so many injuries and not being able to bring anyone in while also losing players.
“You could go to any manager and they would struggle if you took three or four of their main starters out. We’ve lost about 10 players through injuries or being sold.
“I’m here working and trying to get things moving. I’m working day to day to make sure we can compete in every game and try to win some games before the end of the season.”
Ahead of facing Burton Albion at Roots Hall on Saturday afternoon, the Blues boss said: “The last game was a bit of a battle and some of the players will have learnt a lot from it. They wouldn’t have had that type of game before, especially in the Academy.
“It was an old-fashioned back to front game. Some of the young players really stood up and grew. But this game will be totally different.
“It’s more of a footballing game and you will need to be nippy and quick and pass the ball.
“Burton are a passing side who move the ball quickly. We will have to be up for that and penetrate more in the final third.
“We’ve got to get a bit of luck in front of goal and have more conviction. We had a couple of chances against Gillingham and hopefully we can stick one of them away and win this game.
“I want the players to work hard and express themselves. But I want them to enjoy football.
“That’s where we are at the moment and we can’t ask for anymore.”
