Nigel Clough has said that Sheffield United supporters are "desperate" to see their fans reach the final of the FA Cup.
The manager told Sky Sports News: "We've heard a few stories that the Hull supporters are saving themselves for the final.
"Whether that's true or not, we're not sure, but our fans certainly aren't and if we do get there we'll sell out as quickly as we did for the semi-final.
"The supporters are desperate for a bit of success and to see their team on the pitch at Wembley. Any little thing we can use like that, we'll use because we need everything on our side we can get come Sunday."
Arsenal and holders Wigan Athletic meet in the other semi-final later today.
