Ben Garner was pleased with his side's performance after the Addicks recorded a convincing 6-1 triumph over Dartford at Princes Park.
Miles Leaburn bagged a second-half brace in what was the Addicks' first domestic pre-season friendly of the summer, with Charlie Kirk, Jayden Stockley, Sean Clare and Deji Elerewe joining the 18-year-old on the scoresheet.
Following the regulation 90 minutes, an additional half an hour was played to ensure each member of the 22-man squad all got 60 minutes under their belt.
"It was a really pleasing afternoon's work," the Manager told CharltonTV. "We picked two what we thought were balanced teams and played in a slightly different way with each team in terms of the strength of the players, but with the same principles that we wanted.
"Overall, I thought it was really good. Credit to Dartford because I thought they were really competitive."
Garner reserved particular praise for Leaburn, who made an immediate impact after being introduced on 61 minutes.
"It's been a really good week for him," he said. "It was lovely to see him get those two goals.
"He's come in and he's really grown over the last couple of weeks as well - not physically as he's already big enough, but he's grown in confidence and he's grown in belief in what he's doing. I think he has got a really bright future ahead of him."
Meanwhile, the gaffer provided an update on summer signings Conor McGrandles, Steven Sessegnon and Mandela Egbo, as well as Corey Blackett-Taylor.
"Unfortunately we picked up a knock there on Mandela [Egbo] - hopefully that won't be anything serious. Other than that everyone has come through really well and played 60 minutes.
"The two new lads are getting up to speed. Conor McGrandles had a little injury from the end of last season at Lincoln. He's probably a week or so away I'd say.
"Sess has been involved this week but he's not ready to play minutes. He will come into that next week.
"Corey Blackett-Taylor has a very minor knock. He wasn't one worth risking today but again he will come back in and play some minutes next week."
2,775 fans were in attendance at Princes Park and the Manager was delighted with the crowd.
"We want the fans to enjoy coming and watching us play," said Garner. "We want to win as many games as we can because that's what everyone wants. It was really good to see the turnout today and great to see a lot of young fans here as well which was brilliant. We're looking forward to the season."
