Tony Mowbray has said that his Middlesbrough side must be ready for a difficult test against Sunderland this afternoon.
The Boro boss led his team to a one-goal triumph over League Two side Shrewsbury Town in round three, but has told his players that they must be ready to play the role of underdog ahead of their showdown at the Stadium of Light.
"Every club wants to do well and punch above their weight in the FA Cup," he told the club's official website. "This is a weekend when we're going to have to do that if we're going to progress.
"We all dream of getting to the final and we'll be striving to get to the next round. We know it will be a difficult game for us but hopefully it will be difficult for Sunderland.
"We'll go to the Stadium of Light and make sure Sunderland know they've been in a game. Let's hope we have a good day in front of goal."
Middlesbrough are currently in fifth place in the Championship, eight points adrift of first place.
