Karl Robinson was “fuming” with his Charlton players after beating Fulham Under-21s 3-2 at the Valley.
Late goals from Joe Dodoo and Joe Aribo made it back-to-back Checkatrade Trophy wins for the Addicks.
They were trailing for most of the game after Cameron Thompson gave Fulham a second-half lead to cancel out Ben Reeves’ equaliser.
And despite extending their unbeaten run to eight games, Robinson was not happy with his team's performance.
He said: “I’m fuming. I’ve just had a right go at them. When they did what we said, we had chances.
“Our back four were too deep, there were too many backward passes, people not driving into spaces.
“Look, they showed great desire. Our job is to install a quality that’s unrivalled - so that’s not acceptable for us, not acceptable at all.
“We’ve just spoken, we were quite harsh on them maybe, or maybe it’s part of their learning. It’s a ruthless industry.
“The bit I'm happy with is they got themselves out of the mire. Do you know why that was? We played on the front foot, like a Charlton team.
“This forward pressing, being up against the opposition - it’s almost unplayable sometimes. When you get in people’s faces, it makes it difficult for the opposition.”
Academy duo Jo Cummings and Jamie Mascoll impressed on their senior debuts for the club.
The game also saw Mark Marshall, Johnnie Jackson, Reeves, Aribo and Dodoo get some much-needed minutes.
Three further Charlton academy graduates George Lapslie, Reeco Hackett-Fairchild and Taylor Maloney came off the bench, too.
Robinson added: “Do I go away from this learning more? Yes. Do the players? Yes. They’ve had a first-team appearance for Charlton Athletic.
“It’s a dream for people in this area. They've got a chance, ok the attendance wasn't great but people are here to support them. It’s pleasing we’ve won to keep the unbeaten run going.”
