Cardiff City boss Mark Hudson says they're capable of upsetting FA Cup opponents Leeds United today.

It's been 21 years since the Bluebirds recorded one of the biggest F.A Cup upsets of all time when they beat the Whites 2-1 at Ninian Park following goals from Graham Kavanaugh and Scott Young.

Ahead of the cup clash, Hudson highlighted the historical aspect of the tie but admitted that they were underdogs once again against their Premier League opposition.

He said, "I watched their game last night [against West Ham]. I watched a team full of energy right until the last minute. They like to play counter-press football. They've got young energy running through the team and a manager that is extremely enthusiastic about the way they play.

"When you play a Premier League team you will be an underdog, but we have worked on how we can play going forward and how we can get players in the box that can pose a threat.

"It's a team that we've done well against historically and we are looking forward to it."
