Pompey Academy remain in the hunt for the Youth Alliance League title following a 2-0 victory at Newport.
They took an early lead when Alfie Bridgman’s corner was flicked on by Josh Dockerill for Gabriel Kamavuako to hook into the net.
Adam Payce (pictured) then doubled the lead from the penalty spot before the break after Kevin Bosaka had been brought down.
Professional development phase coach Liam Daish said: “We started the game really well, moved the ball quickly and were on the front foot.
“A good first half meant we had a commanding lead at the break, although Newport threw caution to the wind after the break.
"We haven’t had a competitive match for a few weeks, but we stuck together and the boys deserve credit for that."
“They closed us down more and we perhaps could have made things a bit easier for ourselves by being braver on the ball, but the damage had already been done.
“I was really impressed with a lot of the performances, with Toby Steward showing real maturity and calmness between the sticks after returning to the under-18s.
“Josh and Izzy Kaba at centre-back saw us through a difficult patch in the second half and were composed.
"Alfie Bridgman gave us a lot of energy and pace in a more advanced role. He's also picked up more defnesive responsibilities from his time playing at left-back.
“We haven’t had a competitive match for a few weeks, but we stuck together and the boys deserve credit for that.
“With several players out on loan and others involved with the first team, we have been lighter on numbers, but the under-16s who have stepped up haven’t looked out of their depth.”
Pompey: Steward; J.Fox, Kaba, Dockerill, Laidlaw; Bosaka (Hurst 76), Simpson, Aston; Payce, Kamavuako, Bridgman
