5. Ryley Towler - 8
Growing rapidly in front of our hours, with another towering performance which belies his years. What an impressive January acquisition he already looks. Classy with his feet and strong in the air. Photo: None
6. Connor Ogilvie - 7
Dogged defending as ever and such a reliable presence in this Pompey team. Affected little coming forward with the ball, although won two late free-kicks in promising advanced positions. Photo: National World

8. Marlon Pack - 9 - MOM
Sitting deeper in a midfield three has brought out the best in the skipper once more. Conducting the Blues throughout, it was his superb cross from the right which created Bishop’s goal. Flourishing once more. Photo: National World
