9. Abu Kamara - 9 - MOM
(Replaced by Gavin Whyte on 90 mins) From the opening minutes when he tore down the right and set up Bishop for the opener you could tell this would be his day. Ran Wycombe ragged, it looked absolutely effortless. Set up Bishop again for his second and also involved in Saydee’s goal. Photo: Jason Brown
10. Christian Saydee - 8
(Replaced by Kusini Yengi on 81 mins) Involved in the build-up for Pompey’s second goal, releasing Kamara down the right. Then got himself on the scoresheet with a vicious right-footed half-volley from Kamara’s cross. Hitting goal-scoring form at the perfect time. Photo: Jason Brown
11. Paddy Lane - 7
That sensational February form has dipped of late, but the work-rate and quality still remain. Kept ploughing down the left flank, posing questions, and always a threat. Photo: Jason Brown
12. Colby Bishop - 9
Inspired selection. There’s now intense competition for Pompey’s centre-forward spot and what a response. Two lovely first-time finishes from two Abu Kamara crosses in the first-half takes his tally to 18 for the season. Photo: Bryn Lennon
