We can endlessly debate the issues that Manchester United have, but despite the scrutiny on Ralf Rangnick and his team, they have won 5 of their last 8 games and will probably look upon the FA Cup as their chance for some much-needed silverware. With a full-strength team, they should have too much for their Championship opponents, but this will be no walkover.
Chris Wilder has had an instant impact at Middlesbrough, and they will head to Old Trafford in good form, having won 5 of their last 6 games and having conceded just 2 goals in that run. A tight, nervy affair looks likely, and it may take United some time to break down a stubborn Boro defence.
