The Red Devils travelled to Huddersfield with expectations of a routine win but were humbled by the home team.
Jose Mourinho and his players left the stadium still looking shocked after the Premier League newcomers beat them 2-1.
Both Huddersfield’s two goals came before half time and United were forced to try and turn the game around.
Mourinho made two substitutions at half time, bringing on Henrikh Mkhitaryan and Marcus Rashford in the hopes of creating and converting chances.
Rashford managed to get himself on the scoresheet after some good play by Romelu Lukaku but it was not enough to spur the team onwards.
United’s loss was made worse as their fierce rivals Manchester City won against Burnley to open up a five point gap up top.
Despite the poor display and the disappointing attitude, away fans were still hoping to see some of their players show due appreciation.
However, according to Manchester Evening News editor Samuel Luckhurst, only a handful of players stayed back to applaud the away support.
United’s away support are well known for being one of the best away fans and against Huddersfield they made sure they were heard loud and clear.
The home fans also created a remarkable atmosphere to add to the intense match but despite being outnumbered, the away fans were just as loud.
Two goals conceded before half-time didn’t stop the noise but United’s players disappointingly didn’t express their thanks to their fans.
