Southampton booed their team at the final whistle after failing to unlock a Blues defence led brilliantly by man-of-the-match Regan Poole and Conor Shaughnessy.
John Mousinho’s men even had to change their goalkeeper on 26 minutes, with Ben Killip replacing Nicolas Schmid, yet the substitute barely had a save to make.
Indeed, Andre Dozzell came closest with a ninth-minute shot which struck the bar and, despite the match becoming more open in the second half, Pompey claimed a deserved point.
And here are our Pompey player ratings..
5. Connor Ogilvie - 8
Restored to left-back and shrugged his shoulder and got on with it. Such a tremendous competitor, loves a fight and a scrap - and this match was tailor-made for him. Great to have him back. Photo: Graham Hunt
6. Andre Dozzell - 6
(Replaced by Marlon Pack on 71 mins) Neat and tidy and always keeps things simple but didn’t really do enough on the ball in attacking situations. Put in a hell of a shift, though. Photo: Graham Hunt
7. Ebou Adams - 9 - MOM
A new hero is born. Has transformed Pompey’s midfield with his aggression, mobility and quality. Typical bravery earned the equaliser, followed by that memorable celebration sprinting the length of the pitch. Fans also loved his booking when he flew into Robinson. Photo: Stephen Flynn
8. Adrian Segecic - 8
Bang in form and looking like the Aussie who started the season. Buzzed around, chased and harried and never gave Southampton a moment’s peace. High-octane display. Photo: Graham Hunt
