Pete Haynes felt his under-18s side delivered much of the promise they've been showing in the early part of the season in their 8-4 FA Youth Cup second round victory over Portsmouth.
The under-18s will now host Premier League side Arsenal in the third round of the competition after another night of goals at the Jonny-Rocks Stadium.
Callum Ebanks was on target with four strikes, while Charlie Stanton bagged a brace too.
Aaron Evans-Harriott and Toby Lawrence completed the scoring after Cheltenham came from being 3-1 down to earn a memorable win.
"We've said game after game we've been creating loads of chances. We've been defending quite well in recent weeks so we were just waiting for it to click more than anything," Haynes said after the match.
"I think tonight it has clicked in terms of forwards putting balls in the back of the net. Final third quality was there tonight - all things that have been building up over time.
"It has taken the players a bit of time to get the ball rolling in that sense but tonight it came all together really well and to score eight at the Jonny-Rocks is a really good feeling for the lads.
"The challenge we set the players was that at the Eastleigh game everyone had certain roles. Tonight peoples roles and the way they were deployed were slightly different and it's really pleasing that the players were able to take on the information needed to effect the game.
"We were confident going into the game that we knew what we needed to do but it's down to the players to execute.
"Realistically some of them are only two years old in their footballing age, some of them are eight years old in their footballing age, so for them to take on the information that they have done, process it, and adapt to the 3-5-2 Portsmouth went to in the second half was really encouraging and promising.
"The fact they were able to impose their game so well and so assuredly was really pleasing."
