Serge Aurier was a weak link in the North London derby and Pochettino must be ruthless

Tottenham boss Mauricio Pochettino has had to deal with a number of injury problems so far this season, and the Argentine would have been rueing the fact he was missing first-choice right-back Kieran Trippier, as his replacement Serge Aurier struggled in the North London derby.

Arsenal took the lead against their rivals after just 10 minutes as Pierre-Emerick Aubameyang converted a penalty following Jan Vertonghen’s handball, but the free-kick which resulted in Mike Dean giving the spot-kick was thanks to a lazy Aurier tackle after he had been caught out of position.

Spurs did rally though, and they went into the break 2-1 up after a header from Eric Dier and a confident penalty from Harry Kane.

Arsenal boss Unai Emery made two changes at half-time though and the Gunners came out firing in the second half.

It was Aubameyang who netted their second with a beautiful curling strike, meaning the Gabon international had scored from his last 10 shots on target. Goals from Alexandre Lacazette and Lucas Torreira then ensured that Arsenal took the North London bragging rights against a tiring Tottenham side.

Aurier though was extremely poor as Spurs collapsed against their neighbours, with the 25-year-old recording a passing accuracy of just 69 per cent from 26 attempts.

The Ivory Coast international also committed four fouls in the game and made five tackles, proving that he simply doesn’t have the defensive ability or concentration to excel at the top level.

With Trippier ruled out, Pochettino should seriously consider starting 21-year-old Kyle Walker-Peters when the Lilywhites come up against Southampton on Wednesday, with Aurier dropping to the bench after his shocking display.
