Villa now go into next Saturday's clash with in-form Hull City looking to bounce back from successive 3-0 defeats, having been beaten by the same scoreline at the DW Stadium as the one that led to their exit from the FA Cup at the hands of Swansea City.
The visitors created some excellent chances early on, but goals from Gary Roberts, Michael Jacobs and Joe Garner saw the Latics storm to the emphatic victory that leaves the Villans five points off the play-off places.
Hause had something of a debut to forget after coming on in the 63rd minute. The on-loan defender was introduced when the scoreline was 1-0. And while he was, by no means, the only player to struggle, it was not the kind of display that will leave the Villa fans feeling particularly optimistic about his arrival.
And Smith seemed to admit that Hause looked off the pace during the defeat, but suggested that he is still getting up to speed having played so little first-team football since the start of last season.
"I thought it would balance the team up a bit," he told the club's official website when explaining the decision to bring him on. "They let James Chester come out with the ball and he was always on his wrong foot.
"I felt it would be right to get Kortney on with his left foot. He's a bit rusty but the work we'll do in training will push him on."
Villa clearly have the potential to move themselves into the play-off places by the end of the campaign. But they have now conceded 26 goals since Smith arrived, with eight goals shipped in their last three games.
Tommy Elphick's return looked a smart move given his form with Hull. But he did not have the best day on Saturday, and Hause is clearly going to need some time to get up to speed.
But with Villa now 12th in the table, they need to start getting some momentum under their belt as soon as possible - even if the gap between themselves and the top six is not that great at all at this stage.
