Villa face Manchester United at Wembley and Agbonlahor admits the tie will be the biggest game of his career to date.
“Even if it was a different team from the lower leagues playing against United I think it would still be a tight game because it’s a cup final,” he told Sky Sports.
“Obviously form goes out of the window – you’ll just take any sort of win in the cup final.
“You always dream of playing at Wembley so playing in a cup final is a dream come true.”
“(The danger man is) obviously more than any other player, Rooney. The amount of goals he’s scored this season has been second to none,” he added.
“Hopefully we can stop him like we’ve stopped him in the last few games we’ve played and get something out of the game.”
