Villa lost 2-1 to the title contenders in August, but played well and felt hard done by after a series of controversial decisions by referee Kevin Friend.
"We definitely should have got something out of the game down there because we played really well," said Weimann.
"Hopefully we can do that again and get what we deserve this time.
"They are top of the league now so everyone is looking to catch them and we hope we will be able to take points off them.
"I think, attacking-wise, if we are on our game we can hurt anyone and we'll look to do that against Chelsea."
