The 'Villains' beat their rivals 4-2 in a thrilling game at Villa Park on Sunday, moving them to eigth in the Championship after a slow start.
"I always see these games as opportunities and I think the players are now too. We have played some good football at times and look a threat but we just need to tidy up a little," Smith said.
"Our aim is to get into the top two, that was it at the start and where we are now.
"We've won three games on the spin and this group of players know how to win as they did it enough times last season. We just have to keep that belief going.
"Under Steve (Bruce) Villa were good here, not many teams won here, and hopefully that can continue."
