Villa will meet Manchester United in the Carling Cup final after Sir Alex Ferguson's men beat Manchester City 4-3 on aggregate.
The Reds were thankful to goals from Paul Scholes, Michael Carrick and, late on, Wayne Rooney as they overturned a 2-1 semi-final first leg deficit at Old Trafford.
The Claret and Blue will now hope to render United's effort meaningless when they make the trip to Wembley on Sunday February 28.
