Owen Coyle's side are second from bottom and two points adrift in the league, but victory against United would certainly give grounds for optimism and could be a season-defining moment.
Jose Mourinho’s men, meanwhile, are in full stride as they face their second cup fixture in four days. United have not lost an FA Cup away fixture against lower division opposition since 1984.

It’s a big game for…
Wes Brown. The 37-year-old will be facing the club where he started his career and made over 200 appearances for in a 15-year spell. The Manchester born defender won the FA Cup with United in 1999 and 2004 and will be eager to get one over his old side.
The last time the clubs met in the FA Cup Manchester United won 2-0 in 1985.
Two goals from Mortem Gamst Pedersen were enough for Blackburn to record a shocking 2-1 win at Old Trafford.
Player to watch…
Wayne Rooney: The captain has been restricted to mainly appearances in cup competitions this season. Despite this, Manchester United’s all-time record goalscorer has still put in some impressive displays and has revelled in his role of pushing United through the stages.
He opened the scoring in the third round of the FA Cup and equalled Bobby Charlton’s record in the cruising 4-0 victory against Reading. With Rooney expected to line up for United at Ewood Park this weekend, his experience could well be the driving force.

Good afternoon and welcome to The Independent's live coverage of United's trip to Ewood Park. Blackburn sit at the top of the Championship table, but this is the FA Cup so we never say never. Lincoln proved yesterday that anything is impossible and that the underdog should never be underestimated. United are unbeaten if their last six visit's to Blackburn.
Team news coming shortly.
United kick off to get the first half underway. Game on!
Mourinho's men are attempting to assert an early dominance over their relegation battling opponents. The United boss has started with a strong side here today, so it's clear to see they're taking this competition vert seriously. Well, with such an array of quality within the club, it's hard to pick a weak team.
Rashford bombs into the opposing half, but he is quickly surrounded by a sea of Blackburn shirts and dispossessed. The youngster is certainly one to watch today.
Emnes makes the most of a defensive lapse from Smalling and he spreads the ball wide to Conway. The winger bursts forward and delivers a menacing ball into the danger zone, but it's easily collected by Romero.
Young threads a ball through to Mkhitaryan, but Lenihan charges across and comes out on top. The Blackburn defence look strong, at the moment...
The Reds have had 72% of the possession so far.
Emnes picks up the ball in the middle of the park and feeds the ball wide to Feeney. The ball comes into the box, but it's cleared and finds Emnes once again on the edge of the box. The 28-year-old fires a powerful strike towards the goal, but he is denied by Romero.
BLACKBURN 1 - 0 MANCHESTER UNITED
Well that certainly was not written in the script for United and it's Graham with the opener. Emnes picks up the ball in the middle and runs into the final third, before threading a clever ball through to Blackburn's top scorer. He receives the ball and cleverly slots it past a helpless Romero.
Mourinho claps the goal from the sideline.
What a start for Coyle's men.
