The Hatters development squad progressed from the second round of the Bedfordshire FA Senior Cup as they defeated Barton Rovers 4-1 at Sharpenhoe Road.
Goals from Connor Tomlinson, Arthur Read, Drew Richardson and Michael Shamalo gave the Town an unassailable lead, with Ewan Fieldhouse netting a late consolation for the hosts.
The visitors went a goal in front within the opening three minutes, when Tomlinson raced onto Kitan Sorunke's header – the striker burning down on goal before slotting it calmly into the bottom left corner to open the scoring.
With 15 minutes on the clock, Inigo Idiakez's side had doubled their lead, Read twisting and turning before curling the ball into the left corner from 20 yards.
The Hatters had a fantastic opportunity to add to their tally half an hour in when Aaron Jarvis was tripped in the Barton penalty area, resulting in a penalty for the Town.
Frankie Musonda struck it from 12 yards looking for the top left corner, but his powerful effort flew just over the crossbar.
The Town didn't dwell on it though as just two minutes later they had their third – Richardson's 25 yard moving effort caught keeper Charlie Jones out and the stopper could only palm it into the back of his own net.
Idiakez brought on Shamalo and Josh Neufville just after the break and the former was quickest to the ball when Corey Panter crossed in low from Richardson's excellent ball out wide – Shamalo reading the play well and prodding in from close range 58 minutes in.
Harry Isted wasn't able to keep a clean sheet on the night though, as Fieldhouse struck with 15 minutes to go from the edge of the Hatters box, finding the bottom left corner.
Idiakez was impressed with his side's performance, as he said: "Really good again, I have been saying that for the last two months.
"The players from the first team showed a fantastic attitude. We created a number of great chances in the first half – we could have scored six or seven. The second half I have to be honest, it was quite sloppy. But when you are winning 3-0 it is quite normal.
"I am really happy with all of them. We are in good shape, we are training hard, working hard and it's paying off. It was quite a difficult game, but we still played good football. Full credit to the players, it's difficult to come here, to play and create chances and we did."
"This kind of experience from the first team players helps the youth team to grow.
"The help of the first team players with their attitude and the quality they have got, tonight was a good example of them showing good qualities. I think Nathan is doing a great job with the players, because every time they play with the youth team they show a great attitude."
Town line-up: Isted, James, Mead, Musonda, Panter (Jones 61), Richardson, Read, Sorunke, Tomlinson (Shamalo 46), Belgrove (Neufville 46), Jarvis.
