Ruben Amorim received a raptuous welcome from the Old Trafford congregation, then oversaw a helter-skelter victory in his first home as Manchester United’s sixth No 1 of the post-Sir Alex Ferguson era.

Like the five predecessors of the past 11 years, Amorim suffered. Under Europa League lights that shone down on the 6,714 partying Bodø/Glimt support, this was a standard welcome to the Theatre of Thrills and Spills as his new team just about made it through to the win.
