Tottenham Hotspur beat Arsenal 2-0 in a match they controlled throughout.
"I have to blame myself a bit for my header at the far post -- I was kicking myself for missing that -- but we dominated from the start," said Dele Alli.
"It's a huge win for us and the fans. We just have to keep looking to improve. We fell off at the end of last season, so it's important we continue to build on what we're doing."
Harry Kane told Sky Sports: "We wanted to finish the last North London derby on a high note. What a day."
