SUNDERLAND boss Roy Keane is hoping for good fortune and better quality in the final third to shoot down Arsenal tomorrow, writes Joe Johnson.

"We've been working on our final ball and we need to get bodies in the box;" Keane told the Club's official website . "We need to have a go against Arsenal but we'll need a bit of luck as well, you always need that if you are going to beat these top teams."

And the Black Cats manager warned that the Gunners will need to be at the top of their game after seeing Hull take three points away from the Emirates last week. Keane continued: "If anyone says they thought Hull would go and win at Arsenal last week, they are probably lying but that's the beauty of the Premier League, if your not quite at it, these results can happen. Good teams will always have their off days."

Keane also suggested that his side will be a greater challenge than Porto were on Tuesday by stating: "They had a good win in midweek but the Premier League is a different battle ground."

He continued: "I don't think Arsenal were challenged mentally or physically the other night."

After signing three players from north London rivals Tottenham in the summer Keane will be hoping that the prospect of a chance to inflict back-to-back Premier League losses on Arsenal for the first time in 18 months will lead to an improvement upon last weeks defeat against Aston Villa. He said: "We didn't put the ball in the back of the net and that's the hardest thing in football;" The former Manchester United star, who had many battles with the Gunners himself as a player, has called for commitment from his own players.

"They will know we are a decent team and they won't take anything for granted," he added.

"Whatever the result, we want them to know they have been in a good game. As long as we give it our best shot, I'll be happy."
