Villa started the season in fine style but are on a run of five successive defeats without scoring a goal.
We bounced back from last weekend's loss against Newcastle to book our place in the quarter-final of the Capital One Cup with a 2-0 win against Brighton on Wednesday night.
Harry was on target against the Seagulls - his eighth goal in seven cup games - and he feels a good start is key at Villa Park.
"It’s always tough at Villa Park," he said. "They will be fighting for their lives to try and get the points and we have to be ready for that, switched on and hopefully we’ll come away with the three points.
"We have to start fast, get on the ball, get comfortable, try to put them on the back foot, try to score first and look to build from there."
