Vlaar insists belief as well as form will play a huge part as Villa look to fire away from the drop zone in the coming weeks.
He told Villa's website: "We have to believe and show each other that is the only way.
"We are improving. We grow and we improve every day - that is the most important thing.
"You know what you have to do. It all starts with working very hard, giving everything that you have then of course you need the results for confidence. Now we've won so that will help us going-forward for the rest of the season."
