Weimann steered the claret and blues over the Barclays Premier League survival threshold with two goals in Saturday's 3-1 success.
"I think everyone felt the pressure around the ground," said Weimann to Villa's website.
"We needed to win and everyone stepped up. We performed well and got the points that we needed.
"We were playing at home and needed the win so we said we were going to press them for the whole 90 minutes.
"That's what we did and obviously we got a goal after 60 seconds."
