The Blues found themselves 2-0 down after 28 minutes following sloppy defending against struggling Reading, with the Madejski Stadium rocking.
But remarkably, John Mousinho’s men fought back to triumph 3-2 through goals from Tino Anjorin, Colby Bishop and Terry Devlin – and here are our Pompey player ratings...
5. Connor Ogilvie - 7

6. Marlon Pack - 8
(Replaced by Zak Swanson on 70 mins) Wonderful ball over the top to pick out Williams’ run through the middle for the first goal. Used the ball brilliantly overall, dictating the Blues’ play and helping them dominate possession. Photo: Simon Roe
7. Andre Dozzell - 7
(Replaced b Terry Devlin on 70 mins) Along with Pack, helped Pompey dictate the match. Mobility and energy as usual, while uses the ball so well. Photo: Nigel Keene
8. Callum Lang - 7
(Replaced by John Swift on 46 mins) Shrugged off departure rumours. As ever, in the thick of the action, this time scoring 23 minutes into his first friendly of the summer when he converted Murphy's cross. Operating on the right flank, with Segecic in the number 10, he was his usual threat with energy and directness and also assisted for Bishop to grab Pompey’s third. Photo: Jason Brown
