Manchester United put in one of their worst performances of the season on Wednesday night, as they were held to a 0-0 draw by Hull City at Old Trafford.
In a night characterised by poor performances, only one Red Devils star played to his usual capabilities - Michael Carrick controlling play from midfield.
However, manager Jose Mourinho decided to substitute the Englishman at half-time, destroying his team's structure by bringing him off for Wayne Rooney.
And fans were not happy with the decision, with the extremely ineffective Paul Pogba staying on the pitch when taking the Frenchman off would have made much more sense.
