Has Ole Gunnar Solskjaer taken Manchester United as far as he can?
That's the question many United fans are asking after a worrying dip in form that has seen defeats by Young Boys, West Ham and Aston Villa in quick succession.
Other games, such as last week's late Champions League win over Villarreal, and the draw with Everton at the weekend, have seen unconvincing performances.
As Solskjaer approaches three years in the job, some feel it is time for him to be moved aside and a manager with a better trophy-winning pedigree to take United to the next level.
