Pompey Academy produced a devastating display of finishing to rack up a 7-2 Youth Alliance League victory at Yeovil.
The game was originally due to take place earlier in the month, only for heavy rain to see it abandoned at the break with the Blues leading by two goals.
But they shook off that disappointment and roared into an early advantage, courtesy of goals from Dan Cadman and Harry Anderson.
The latter had a chance to score again from the penalty spot, but was twice denied by the Glovers keeper, who had moved too quickly off his line for the first attempt.
Instead it was Kristian Dawson who added the next goal by converting a delivery from Harrison Brook.
Anderson made it 4-0 at the break, although the hosts were able to reduce their deficit when the action restarted.
Charlie Bell (pictured) was next to get in on the act and after the Glovers made it 5-2, Harvey Rew and Brook completed the rout.
Professional development phase coach Liam Daish said: “We had gone to Chelsea’s training ground for a friendly on Friday and it was a bit like Disneyland with all their facilities.
"Everyone brought something to the table and their application was first class, while we played the game in the right manner."
“So, with all due respect to Yeovil, this was a completely different environment, but the boys remained professional and produced a good performance.
“We were very much on the front foot throughout the contest, working extremely hard both in and out of possession.
“The lads went out there with the right attitude and got exactly what they deserved. I’m delighted for them.
“There were plenty of chances created and we could have scored even more, but the goals we did get were well taken.
“Everyone brought something to the table and their application was first class, while we played the game in the right manner.
“I thought that Harry Jewitt-White was the standout performer, showcasing his energy after returning from a Welsh training camp.
“We also brought on Elliott Simpson and Benjani from the under-16s in the second half. It was their first real involvement at this level and they both looked bright.”
