It appeared John Mousinho’s men would be on the end of a battering when, in the opening 10 minutes, Leeds took the lead through Pascal Struijk and hit the bar three times.
Yet, out of nowhere and entirely against the run of play, the Blues found themselves 2-1 in front at the break through debutant Elias Sorensen and Callum Lang.
Within 56 seconds of the restart, it was 2-2 with Wilfried Gnonto levelling – but more drama was to come.
Lang grabbed his second in the 93rd minute from the penalty spot after good work from Christian Saydee as Pompey led again, only for substitute Brenden Aaronson to make it 3-3 in the 96th minute.
Still, an excellent point for the Blues, and here are our player ratings...
