Acheampong opened the scoring with a superb header for Chelsea's 3-0 on Saturday.
Afterwards, the defender paid tribute to skipper Reece James, stating: "It’s that inspiration to know you can come through the Academy and play for Chelsea first team.
"I’m so grateful to Reece and all the other Academy players because they’ve given me lots of support.
"It was a really good feeling to score. It’s quite surreal. I don’t remember it too much, but just a really good feeling. I don’t really remember much of the celebrations either, to be honest. I need to watch it back!
"I don’t score many goals, so to score my first Chelsea goal is really good."
He also told Chelseafc.com: "The first half was quite tough and they created quite a lot of chances, but so did we. I’m happy we managed to get that first goal, and hopefully we can build from there."
He added: "Of course, we’re really pleased with the win. We spoke about building on this, and hopefully we can do the same in the games to come."
