Leeds United defender Jason Crowe admits the players were shocked by their achievement in dumping Manchester United out of the FA Cup.

Crowe insists the surprise of his team's ­giant-killing left him open-mouthed at the final whistle at Old Trafford.

Crowe said: "We always knew it was going to be tough, but we also knew we could give them a game. But what a fantastic feeling. I didn't know what to say at the end!

"We gave United a good game and were delighted to win.

"We stayed strong as a unit and managed to keep a clean sheet.

"It was brilliant. You want to play in those games week in, week out. The dressing room was a fantastic place afterwards."

Crowe reckons beating Sir Alex Ferguson's side can inspire Leeds to go on and win promotion to the Championship.

He added: "To go to a place like that and win gives you an incredible feeling.

"If you have a good cup run, it breeds confidence and that can turn into a good league run as well."
