Tottenham manager Ange Postecoglou has explained his bold double substitution at half-time against Arsenal was in response to a poor opening 45 minutes. Spurs took the lead, slightly against the run of play, in the north London derby when Heung-min Son's deflected effort found the bottom corner to stun the majority inside the Emirates Stadium.

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

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. Son Heung-min gave Tottenham a 25th-minute lead against the run of play but in the end the scoreline flattered Postecoglou's side who have now won only once in nine league games.

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.
