Ange Postecoglou says improving Tottenham's defending at set pieces is "my burden to carry" after Gabriel Magalhaes scored from a corner to settle Sunday's north London derby.
The Brazilian eased Cristian Romero aside to head home Bukayo Saka's inswinging corner in the 64th minute and give Arsenal a third consecutive win at the home of their rivals for the first time since the 1980s.
