Manchester United were booed off the pitch as Norwich earned a shock victory at Old Trafford, increasing the pressure on manager Louis van Gaal.
Despite all of United's possession, it was Norwich who look the lead in the first half through Cameron Jerome.
It got worse for the home side in the second half as Jerome broke clear to feed Alex Tettey, who poked in.
Anthony Martial pulled a goal back, but United's winless run is now six games while Norwich are out of the drop zone.
Juan Mata saw a free-kick from the edge of the area pushed away by Declan Rudd as the hosts went in search of the equaliser in the second half.
Centre-back Chris Smalling could have earned a point late on, but headed narrowly wide as United dropped to fifth in the Premier League table.
