Arsenal overcame the hurdle of a north London derby and an anxious finale to maintain momentum in the Premier League title pursuit with a vital victory at Totteham.
Arsenal were then thrown off course when a dreadful clearance by goalkeeper David Raya presented Cristian Romero with a goal after 64 minutes, the nerves really jangling when Heung-Min Son scored from the spot three minutes from the end of normal time after Declan Rice fouled Ben Davies.
It was all so different when Arsenal went ahead after 15 minutes as the recalled Pierre-Emile Hojbjerg glanced Bukayo Saka’s corner into his own net, the England forward crowning a sweeping counter-attack with a smooth finish for the second after 27 minutes.
