Last year's Champions League winners are targeting a victory which would all but secure a return to a place among Europe's elite next term, while Villa's Barclays Premier League place is still to be confirmed despite two wins which have taken them clear of the relegation zone.
"We played them at home and we got a convincing result there," said Cahill, who began his career at Villa before joining Bolton in January 2008.
"This time around it will be a different team we face. They're playing some good football at the minute. Attacking-wise they look very strong.
"It's going to be tough, but I'm looking forward to going back to my old club and looking forward to the game."
