In a repeat of Monday's heartbreaking finish at White Hart Lane, Villa reserves were denied all three points by a late, late equaliser.

Toby Mikaelsson's 79th minute strike looked to have maintained Villa's 100 per cent start to the season. But Djimi Traore struck deep into stoppage-time.

Earlier the impressive Zoltan Stieber had put Villa ahead from the penalty spot, before Matty Taylor drew the hosts level.

A slow start to the action saw neither keeper called into action in the early stages.

Yago Bellon latched onto Stieber's left-wing centre on eight, but Crainie stepped in to clear for the hosts.

Davies, who scored on his reserves debut last month, met another Stieber cross three minutes later, but headed over the bar.

Villa had a penalty on 11 as Mikaelsson proved too tricky for Traore. Stieber made no mistake as he drove into the corner from the spot.

England striker Nugent fired unconvincingly straight at Sorensen on 20.

The Villa keeper comfortably gathered a long range effort from Songo'o four minutes later.

O'Halloran was then unable to connect with another Stieber centre as Villa searched for a second.

Mikaelsson pounced on a loose backpass from Lauren on 26, but Hogg was unable to connect with the young Swede's low cross.

Damian Bellon produced a powerful run into the box on 32 and squared for Earls, whose shot was blocked by Primus.

Mikaelsson fired weakly at Ashdown on 34 after good work down the right flank from Yago Bellon.

Crainie headed Stieber's cross from the left behind on 42 as Mikaelsson waited to pounce at the far post.

Lund tracked back to deflect Taylor's rising effort behind for a corner on 45.

Taylor sent a left-foot free-kick straight at Sorensen two minutes after the interval.

Damian Bellon brought Ashdown into action on 50, the Pompey keeper doing well to palm a thunderous drive behind for a corner.

Stieber rattled the bar with a well struck free-kick on 54. Damian Bellon fired over from the rebound.

Villa's bright start to the second-half continued with Stieber looking increasingly dangerous.

Kallon raced down the right on 66, but saw his centre headed behind for a corner.

Taylor levelled matters for the hosts on 73 as he met a Mendes corner and forced the ball home.

Mikaelsson raced into the box in an effort to restore Villa's lead a minute later, but he was denied by Crainie.

Mikaelsson did score Villa's second on 79, slotting past Ashdown after more impressive work down the left from Stieber.

Stieber played a neat one-two with substitute Collins on 82, but fired a tame shot straight at Ashdown.

Sorensen raced off his line to beat Nugent to a long clearance from Ashdown.

Delfouneso ran onto a deft flick from Collins on 83, but fired into the side netting.

Davies showed great awareness to deny Traore two minutes later as Pompey chased a second equaliser.

Mendes fired over the bar from the edge of the box on 89 as he met a cut-back from Taylor.

Lowry blocked a rising drive from Songo'o in stoppage time. But the hosts were level seconds later as Traore met a Mendes corner to steal a point.
