Jose Mourinho has officially left his post as Manchester United manager.The Portuguese boss was sacked after a tumultuous start to the season.Although Man United qualified for the Champions League knockout rounds, it's fair to say they have been underwhelming in the Premier League.The Manchester club currently occupy sixth in the Premier League, 11 points off the top four and a further eight points off the top of the table.That caused United to act as they sacked him on Tuesday, with Ole Gunnar Solskjaer named as his replacement."Manchester United announces that manager Jose Mourinho has left the club with immediate effect," Man United's statement read, per Manchester Evening News."The club would like to thank Jose for his work during his time at Manchester United and to wish him success in the future."Mourinho was said to have a poor relationship with many at Man United, including Paul Pogba and Anthony Martial.But, he's also said to have angered senior officials during his time at the club.In explaining his demise, The Times have revealed a story of how Mourinho left senior figures 'appalled' at the 60th anniversary memorial of the Munich air disaster in February.Instead of turning up in a suit and tie, Mourinho instead decided to wear a hoodie and trainers, which did not go down well at all.Paul Hirst of the Times writes: "When Mourinho turned up to the 60th anniversary memorial of the Munich air disaster wearing dark trainers with a garish white trim on them, and a hoodie under his club suit, some senior figures were appalled."Nobody had the gumption to tell him to put on a pair of smart shoes and ditch the hoodie, though. This was Mourinho. He did what he wanted."You can view his attire from the day below:

The Telegraph go on to add that he was expected to wear a collar and tie, and his attire served as further proof to senior figures that he did 'not get the club'.

Ian Ladyman of the Daily Mail then backed up the story by claiming his choice of clothing was an 'abysmal sight'.

It's amazing that this news has only just emerged now, almost nine months on from the day.

Nevertheless, it's understandable that United figures were not happy with Mourinho and the attire could well have added to their decision to sack him on Tuesday.
