Pompey are tantalisingly close to Championship safety after registering a third successive victory.
Ibane Bowat, on as a substitute for the injured Terry Devlin, grabbed a 63rd-minute winner from Adrian Segecic’s corner to put Leicester City on course for League One.
For John Mousinho’s men, however, are now seven points clear of the drop zone with three matches remaining as this remarkable late-season surge continues.
And here are our Pompey player ratings…
9. Milli Alli - 6
One of his quiet days. Had a glorious chance in the 58th minute with a one-on-one, yet didn’t even get a shot off. Yet performance levels dropped off alarmingly in the second half, prompting frustration from the Fratton faithful. | Simon Roe/ProSportsImages
10. Conor Chaplin - 8
(Replaced by Ebou Adams on 77 mins) - Recalled to the side after being ineligible to face parent club Ipswich and you could see why. Buzzed around, wanted the ball, a constant threat and the Chaplin we all know and love. | Jez Tighe
11. Keshi Anderson - 6
(Replaced by Adrian Segecic on 8 mins) Forced off early with what appeared to be a hamstring injury. You fear his season is now over. | Graham Hunt/ProSportsImages
12. Colby Bishop - 8 - MOM
Finishing the season strongly, just needs some more goals. Excellent link-up play play, teed up Alli and Segecic for chances they should have scored from and caused problems throughout. | Jez Tighe
