The Austrian Under-21 player has made an instant impact since breaking into the Villa first team with the winner against Fulham and a spectacular goal in Monday's draw against Stoke. Now Weimann is hoping Villa can repeat their surprise win at Chelsea and draw at Liverpool when they face the Red Devils.
He said: "We are all looking forward because Old Trafford is a brilliant place and I think we will go there positive.
"They are the games as a young player you want to play in and I've never been to Old Trafford so to be involved will be brilliant.
"Manchester United have been a top team for years and to go there is special. But we are not going there thinking we are going to lose. We are going to try and get something out of the game.
"It's not long ago that Gabby (Agbonlahor) scored the winner there so why not again? We drew against a big club away in Liverpool and won at another in Chelsea so why can't we do it again."
