Ange Postecoglou described Tottenham Hotspur's dismal Premier League campaign as unacceptable after they slumped to a lame 2-1 defeat at north London rivals Arsenal on Wednesday.

Leandro Trossard transformed the mood at Arsenal with the winning goal as they recovered from an early setback to beat Tottenham Hotspur 2-1 at home and move back into second place in the Premier League on Wednesday.

With six defeats in their past 10 games, a loss to their biggest rivals and closer to the relegation zone than the top four, things are going from bad to worse for Tottenham.

Ange Postecoglou said he hopes his Tottenham players are hurting after their 2-1 defeat to Arsenal on Wednesday and labelled the performance "unacceptable."

Tottenham Hotspur head coach Ange Postecoglou says his side’s league form “can’t be accepted by anyone at the club” after a 2-1 north London derby defeat to Arsenal on Wednesday. Spurs took the lead through captain Son Heung-min in the 25th minute but an own goal from Dominic Solanke and a strike from Leandro Trossard meant that Arsenal took the lead into half-time and did not relinquish it after the break.

Mikel Arteta hailed Arsenal's sensational display after they bounced back from recent cup disappointment to win 2-1 at home to Tottenham and reignite their Premier League title hopes. Arsenal dominated the opening exchanges but failed to make a number of set-pieces count and were hit by sucker-punch in the 25th minute when a deflected effort by Spurs captain Son Heung-min found the bottom corner.
