Tottenham striker Jermain Defoe says it's wrong to say Arsenal are on the slide.

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."
