Arsenal vs Tottenham result: Pierre-Emerick Aubameyang rescues point in pulsating derby - 5 things we learned

Arsenal 2-2 Tottenham: Christian Eriksen and Harry Kane had given the visitors a 2-0 lead but Alexandre Lacazette and Aubameyang salvaged a point

Pierre-Emerick Aubameyang rescued a point for Arsenal to clinch a 2-2 draw against Tottenham in a pulsating north London derby.

Spurs ruthlessly took their chances in a first half with Christian Eriksen and Harry Kane putting the visitors into a 2-0 lead.

But Alexandre Lacazette gave the Gunners hope heading into the break, utilising his quick feet before rifling past Hugo Lloris to halve the deficit.

Kane then struck the post from a tight angle, with Sead Kolasinac missing from close range on the stretch as Pierre-Emerick Aubameyang waited to convert.

The Gabonese forward did not have to wait long for his goal though, redirecting Matteo Guendouzi's clever cross into the corner at the near post as a live Emirates Stadium erupted.

The Gunners thought they had won it when Sokratis Papastathopoulos converted from close range but VAR ruled it out after Sead Kolasinac strayed offside in the build-up. Here are five things we learned from the Emirates.

Emirates turns up the volume

The first north London derby of the season produced one of the better atmospheres seen at the Emirates in recent years.

Often maligned for its lack of atmosphere, Arsenal fans turned up the volume once again in what has been a promising trend this season.

Even after Christian Eriksen's opener and Harry Kane's penalty to make it 2-0, they responded superbly to lift their side, helping to facilitate the quick tempo Unai Emery wants from his players.

Sanchez endures torrid time at right-back

Arsenal electric start to the game was made possible by Davinson Sanchez being flustered playing out of position at right-back.

The Colombian failed to stem the tide as the Gunners sent wave after wave of attack down his side, with the trend continuing even after Christian Eriksen's opener.

Pierre-Emerick Aubameyang drifted to the left and his quick feet repeatedly carved out space for himself to deliver into the box, with Sanchez's sluggishness allowing a pinpoint delivery that Nicolas Pepe almost headed home, only for Danny Rose to deny him with an instinctive block from close range.

The second half, while better, still included mistakes, including a poor header back towards goal that Henrikh Mkhitaryan failed to capitalise on.

Kieran Trippier's alarming drop-off last season meant his sale was understandable, but with Serge Aurier unreliable and injuries to Juan Foyth and Kyle Walker-Peters, Mauricio Pochettino may have created an ongoing problem for himself after failing to sign a replacement.

Luiz creates more uncertainty

After his horror show at Anfield last week, David Luiz was required to remain calm in his first north London derby.

Yet after a storming start from the Gunners, the Brazilian helped create danger for his own side, which Spurs ruthlessly exposed for the opening goal from Christian Eriksen.

After misjudgements from Sokratis Papastathopoulos and Granit Xhaka, Luiz's aggression hurt Unai Emery's side once more, attempting to intercept on the half-way line, but committing too much as Son Heung-min executed an intricate back heel to leave Arsenal totally exposed.

Luiz at his best is when his judgement is spot on, but here once more it was woefully short of what is required at this level. Erik Lamela profited with the rebound from his effort gleefully dispatched by Eriksen. Soon enough Emery will have to make a judgement on Luiz and whether the current destabilising effect he is having on an already vulnerable defence is worthwhile.

Kane does it again in north London derby

Harry Kane's penalty to put Spurs 2-0 lifted him into a tie for top goalscorer in north London derby history.

With 10 goals, Kane, still only 26 years old, is level with Bobby Smith and Emmanuel Adebayor.

He'll have to wait to take the record for himself though, with the width of the post denying him a second in the game after driving across goal from the right side of the penalty area.

Leno spotlight intensifies

Bernd Leno appears to have a glaring weakness in his game, which Spurs profited from once and should have done so again.

The German's inability to either hold shots from range, or judge how much power he should apply when parrying the ball, created needless danger.

First to set up Christian Eriksen's opener after failing to hold the tamest of shots from Erik Lamela. Then Harry Kane's bobbling effort directed towards the near post, which was pushed into the direction of Son Heung-min, who failed to shoot immediately, therefore allowing Arsenal to eventually recover and crowd out the danger following the subsequent cutback.
