Keane's side could have struck up a bigger winning margin had their finishing in both the first and second half not been so poor.
Roy O'Donovan failed to direct his header from Murphy's cross on 26 and just 10 minutes later Andy Reid failed to hit the target from a free-kick in a good position.
Villa did have a couple of chances in the first 45 minutes, notably an acrobatic effort from John Carew which sailed just wide and a dipping free-kick from Shaun Maloney which failed to hit the target.
Big Norwegian Carew did manage to bring one save out of Gordon as his shot on the turn nearly caught the Scot out.
The second half began in much the same vein as the first, with neither side showcasing any sort of passing ability.

Villa were still getting nowhere and the chants of "Feed the Hare and he will score" were getting louder. Martin O'Neill couldn't resist the pressure and the ineffective Agbonlahor looked set to be replaced.
However, O'Neill had other ideas and a strange substitution saw Nigel Reo-Coker withdrawn. That left Agbonlahor on the right with Ashley Young playing in an unfamiliar central midfield role.
The manager eventually realised his mistake as he replaced Maloney with Isaiah Osbourne, switching Young to the left wing.

With Carew still looking like he'd eaten too many Easter eggs and Young's play resembling that of the festival bunny, Villa continued to struggle.
And after Grant Leadbitter missed a good chance by a considerable distance it appeared to signal that it wouldn't be
The finish was reminiscent of Chopra's former team-mate Michael Owen as he needed took a couple of touches and finished in a composed manner.
