Alex McLeish will surely have no hesitation in fielding the Irishman at the Emirates, especially against an Arsenal side that are likely to rest Robin Van Persie and were largely outplayed by Manchester United on Sunday.
Villa do look too big at odds of 5/1 (Paddy Power £100 free bets) considering that Leeds held their own for much of the third round match at the Emirates, not to mention the fact that the Midlands club won at Stamford Bridge less than a month ago.
Keane scored a couple of excellent goals against Wolves and he is a 10/1 chance (bet365 bookmaker) to break the deadlock in this encounter, with Darren Bent also likely to test the Arsenal defence with his pace. This could be an effective attacking duo for the visitors against a team missing Thomas Vermaelen.
Arsenal are a best price 8/13 (Ladbrokes free bet) and those odds seem a little skinny, although Thierry Henry should be back in the squad after missing the United match with injury. However, the absence of Mikel Arteta means that the Gunners might struggle to create chances.
Perhaps the best way forward in this match is to lay Arsenal on betfair at odds of 1.66 as there are too many question marks over the team’s ability to create and score chances without their Dutch artist.
