Arsenal boss Arsene Wenger knows they can deliver a psychological blow to title rivals this weekend.
Victory at Cardiff on Saturday, when England left-back Kieran Gibbs is set to be available again following illness, could see the Gunners move seven points clear, with their leading rivals all not in action until Sunday.
Wenger said: "We have that opportunity we want to grab at the moment.
"We are in a position where we do not need to look too much at the other results, just at our results, that is a luxury and of course we want to take advantage of that."
