Gus Poyet: "We cannot underestimate Bradford"

Sunderland boss Gus Poyet is adamant that his side cannot afford to underestimate Bradford City in their match in the fifth round of the FA Cup.

The Bantams provided the shock of the competition as they knocked Chelsea out courtesy of a 4-2 victory at Stamford Bridge.

Poyet feels that his side will have to be at their best as he believes the match will be unlike any other challenge they have faced this season.

He told the club's official website: "We cannot underestimate Bradford for many reasons and for sure it is going to be a difficult game to analyse, because there are so many things in play and so many circumstances that can influence the game.

"It is going to be very, very different to any game we have played so far, but we will try to find a way to win because we want to do well in the cup."
