Manchester United are now without a win in their last six games in all competitions after losing 2-1 at home to Norwich City in the Premier League on Saturday afternoon.
Cameron Jerome opened the scoring for the visitors in the latter stages of the first period, before Alexander Tettey made it 2-0 in the 54th minute.
Man United had hope when Anthony Martial netted in the 66th minute, but that was where the scoring finished as the Red Devils dropped out of the top four in the Premier League.
The home side dominated possession in the first 45 minutes, but chances were few and far between and it was Norwich that broke the deadlock in the 38th minute when Cameron poked past David de Gea from inside the box.
Boos rung out around the stadium at the break, but things did not improve in the second half as Tettey's low effort in the 54th minute wrong-footed De Gea and ended up in the bottom corner.
Man United, who are now without a win in their last four in the league - two of which have been defeats - responded through Martial, the Frenchman firing home from inside the box after scrappy defending from Norwich.
Ashley Young and Chris Smalling both had chances to level in the minutes that followed, but Norwich held firm to win their first-ever Premier League match at Old Trafford.
There were more boos at the final whistle as Louis van Gaal left the field, and his team are showing no signs of improvement as the all-important Christmas period approaches.
As for Norwich, who managed four attempts on target to Man United's two, they are now out of the relegation zone following the surprise three points.
