Played behind closed doors at the Blues’ Hilsea training ground, the fixture consisted of two 60-minute periods, with John Mousinho’s men using 22 players.
However, it was the League One Chairboys who ran out emphatic winners through goals from Garath McCleary, Richard Kone, Beryly Lubala and an unnamed player.
Mousinho was understandably angry after the final whistle – and here are our Pompey player ratings...
9. Paddy Lane - 5
(Replaced by Gavin Whyte on 61 mins) Restored to the right wing in pre-season following the departure of Abu Kamara, yet Wycombe was his most disappointing display of the summer so far. Offered little creativity, but always puts in a shift and prepared to work back. Photo: Jason Brown
10. Callum Lang - 5
(Replaced Sammy Silvera on 61 mins) Not quite clicked for the energetic attacker in pre-season yet and still searching for his first goal. Couldn't make any inroads into Wycombe during his time on the pitch, spending his time chasing and pressing rather than trying to affect matters with the ball. Photo: Jason Brown
11. Josh Murphy - 6
(Replaced by Harry Clout on 61 mins) An encouraging pre-season has definitely whetted the appetite of supporters over what the ex-Oxford man will bring to the team. Put in some decent crosses from the left, but all at the near post with no team-mate making that run. Perhaps that actually raises questions about his team-mates rather than his delivery.

12. Jordan Archer - 6
(Replaced Will Norris on 61 mins) Had no chance with either of the two goals which occurred during his time on pitch. The first was bundled in at close range after a free-kick was headed back at the far post. The second was a lovely curling right-footed shot which was unstoppable. Took one towering take inside the six-yard box during one impressive moment. Photo: Habibur Rahman
