Ralf Rangnick has insisted that overhauling the style of a team will always take time - and warned Manchester United fans of more bumps in the road.
The 63-year-old was named as United’s interim boss at the end of November, after Ole Gunnar Solskjaer was sacked amid a wretched run of Premier League form.
Rangnick initially steadied the ship in terms of results since his appointment, although performances often left a great deal to be desired.
