Spurs ace Defoe: You can't write off Arsenal
Defoe is worried about taking Sunday's opponents lightly despite their recent poor form.
"I've always said they're a good team," he said.
"You can't write Arsenal off. In football it's always the next game, you can change it in the next one. And I think, playing against us, it'll be a different Arsenal from what people have seen over the last few weeks."
