Manchester United's reunion with Cristiano Ronaldo has not gone the way that either party would have hoped.
Since the appointment of Ralf Rangnick, the forward has only scored two non-penalty goals with another coming from the spot and overall in the league, he has failed to be the driving force to win United the league that many pundits claimed he would be. His enforced absence from the starting XI that lost 4-1 at Manchester City offered a suggestion of what life without the Portuguese would look like.
United's galling derby-day defeat has left Ralf Rangnick's side 22 points behind leaders City and the gap between themselves and City and Liverpool is vast. So where has it gone wrong - and what role does Ronaldo play in this?
