Manchester United suffered a 2-1 defeat at Nottingham Forest on Saturday as the home side piled more misery on their beleaguered visitors with goals from Nicolas Dominguez and Morgan Gibbs-White securing the points at a rocking City Ground.
Erik ten Hag's United team are struggling in seventh on 31 points after their 14th defeat this season in all competitions. It was Forest's first Premier League win over United since 1994.
The visitors were coming off an uplifting 3-2 victory at home to Aston Villa on Boxing Day that saw them recover from two goals down, but their inconsistency struck again and they were terrible at times on Saturday both in attack and defence.
Dominguez broke the deadlock in what had been a drab game after 64 minutes with a shot from the centre of the box.
Marcus Rashford equalised in the 78th when Alejandro Garnacho pounced on a poor clearance from goalkeeper Matt Turner and sent a precise pass across the edge of the 18-yard box to Rashford who fired into the bottom right corner.
United's celebrations were short-lived however as Gibbs-White curled a superb shot into the corner on the counter-attack after Turner had made a great save at the other end.
The victory means Nuno Espirito Santo's Forest, who won back-to-back games for the first time this season, are 15th on 20 points after 20 matches, five points clear of the drop zone.
