Agbonlahor adamant Villa still in Capital One Cup
Villa gave Blackburn a 2-0 start in the semi-final second leg three years ago but hit six goals in an hour to storm through.
And striker Agbonlahor, 26, is convinced they will knock League Two Bradford out in the January 22 return.
He said: "We came back to win 6-4 in the end to reach the Carling Cup final in 2010 so we're not out of it.
"This is only half-time and over two legs we'll put it right."
