It is hard to argue against the fact that Manchester United has regressed since Sir Alex Ferguson retired back in 2013.
Up until the appointment of Jose Mourinho, United had not come close to success on the European or domestic stage since his managerial departure. However, progress looked like it was being made when the Portuguese boss led the Reds to the 2016/17 Europa League, League Cup and Community Shield.
The silverware was seen as a stepping stone for United on their path to a return to the glory days. Fast forward to March 2018 and those hopes appeared to have unravelled.
