Pompey Academy returned to winning ways in the Youth Alliance League with a 3-2 victory at Cheltenham.
It meant the young Blues completed a double over their opponents and gained some revenge for their 8-4 defeat in the cup last month.
The visitors started brightly and Charlie Bell crossed for the prolific Alfie Stanley to score his 20th goal of the season.
Stan Bridgman then converted a corner to double the lead, only for the Robins to hit back and level by the break.
Pompey recovered from that setback, however, and some good pressing allowed Bell (pictured) to grab the winner.
Professional development phase coach Liam Daish said: “I was very pleased with how we played and the start, in particular, was the best I’ve seen for a long time.
“The boys worked as a collective and produced plenty of effort, with some good goals scored by Alfie and Stan.
"I was very pleased with how we played and the start, in particular, was the best I’ve seen for a long time."
“Our opponents got back into, although we were quite unfortunate on both occasions that we conceded.
“Again we reacted positively after the break, making more of the right decisions to really set the tone.
“Our pressing was excellent and really forced Cheltenham into making mistakes – something we’ve been guilty of ourselves in recent weeks.
“Charlie got what proved to be the winner and we saw the game out against a side that are always difficult to play against.
“The conditions were tough, but we showed plenty of resilience and managed to showcase some good stuff in Cheltenham’s half.
“It was also nice to have Haji Mnoga and Tom Bruce back in the fold. Their defensive qualities are important for us and hopefully they can remain fit for the rest of the season.”
