The Hatters hadn’t won for 13 matches and were bottom before kick-off, yet claimed a comfortable 1-0 success over John Mousinho’s men to seize a relegation lifeline.
Pompey can have no complaints, not mustering a shot on target and failing to test home keeper Thomas Kaminski, who enjoyed an easy afternoon.
And here are our Pompey player ratings...
5. Connor Ogilvie - 6
Tremendous block on Brown in the first half as the striker attempted to race through. Had glorious chance to score, only to plant a free header from Saydee cross over the bar. Was the Blues’ best opportunity and could have been the hero. Photo: Jason Brown
6. Andre Dozzell - 5
Picked up an early booking following an awful challenge on Liam Walsh but stuck at it. Nature of the game meant he didn’t enjoy much possession, spending his time chasing and harrying. Photo: Jason Brown
7. Isaac Hayden - 5
(Replaced by Terry Devlin on 81 mins) Survived last week’s injury scare and the challenge of the fit-again Potts to retain his place. However, couldn’t get any foothold in the game and it largely passed him by. Completely anonymous. Photo: Jason Brown
8. Matt Ritchie - 5
(Replaced by Kaide Gordon on 46 mins) Just couldn’t get involved, certainly was unable to provide any sort of attacking threat down the right. Unsurprisingly substituted at half-time. Photo: Jason Brown
