The Blues hadn’t lost since March stretching 27 matches, but suffered a 4-0 hammering at the hands of the Tangerines, with skipper Joe Morrell also seeing red.
It was an appalling second-half display from John Mousinho’s men, who have also been knocked off the top of League One by Bolton. Here’s our Pompey player ratings...
5. Jack Sparkes - 4
Beaten far too easily for cross which led to opening goal then, at the other end, involved with Dan Grimshaw pulling off two good saves in the same first-half. Overall, though, defensively really struggled. Photo: Jason Brown
6. Joe Morrell - 5 - SENT OFF
Was having a decent game until earning a second yellow card in the 64th minute following a foul on Dembele. Can have no complaints either. Second red card of the season means a longer ban. Photo: Jason Brown
7. Alex Robertson - 6
(Replaced by Marlon Pack on 80 mins) Was a delight at times in the first half, when Pompey looked at their best, pinging the ball around and driving from midfield. But like his team-mates, performance, dipped alarmingly after the break. Photo: Jason Brown
8. Paddy Lane - 6
(Replaced by Terry Devlin on 69 mins) Very bright in the first half with the best Pompey action coming down the right. Put one delightful ball across the six-yard box which no-one was on the end of. Photo: Jason Brown
