Arsenal visit Elland Road this weekend looking to maintain their top-of-the-table position. Martin Keown has been lost to a hamstring injury (2-3 weeks) and Edu (groin) continues to be sidelined. Ray Parlour (hamstring) will face a fitness test. Dominic Matteo (knee) has missed the last two matches, and Michael Bridges twisted a knee the day before last week's Blackburn loss. Alan Smith has a minor ankle knock that is not expected to sideline him.
