Ange Postecoglou blamed himself for Tottenham's derby defeat against Arsenal - but insisted they will keep plugging away with their gung-ho style.
Tottenham had lead after Son Heung-min's 25th-minute goal but went in 2-1 down at half-time after an own goal from Dominic Solanke and Leandro Trossard's bottom-corner strike.
Spurs came out all guns blazing as Brennan Johnson and James Maddison came on for the second half but Postecoglou's attack-first men managed just two shots on target all evening.
Their second derby shortfall of the season leaves them languishing 13th in the Premier League with 11 defeats - a personal record for this stage of the campaign and more than Ipswich Town.
