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."

Myles Lewis-Skelly became the second-youngest Arsenal player to start in a North London derby in the Premier League (18y 111d), after Cesc Fabregas, who started home and away as a 17-year-old in the 2004-05 campaign.
