Tottenham boss Andre Villas-Boas says form goes out the window for their derby against Arsenal.
Villas-Boas does not subscribe to the theory that Arsenal are in free fall under Wenger, however.
"Their position (in the league) is completely irrelevant," he said.
"Last season they had a poor start and managed to clinch third spot by picking up points. You drop three points, you are condemned.
"This is the nature of the Premier League."
