Sunderland winger Adam Johnson has called on his side to take the game to Bradford City in their FA Cup match at Valley Parade .

The Bantams defeated Chelsea in the last round to produce the shock of the competition, and Johnson has warned his side that they will face an extremely tough task to beat Phil Parkinson's men and reach the quarter-finals.

Johnson told the club's official website: "We have to go there and do everything right because if you take it for granted anything can happen in the FA Cup.

"They are going to be up for it and their fans are going to be right behind them, so need to go there and play our game in difficult conditions and be at our best because if we do that we will come out on top.

"They beat Chelsea in the last round and that can happen to anyone so we need to go there and put Tuesday's result behind us, and go on the front foot straight away to put them under pressure."

Sunderland have reached the quarter-finals of the FA Cup twice in the past three seasons.
