Ralf Rangnick branded Manchester United's 4-0 thrashing by Brighton as 'humiliating' and 'unacceptable'.
United conceded four goals for the sixth time in their last 30 Premier League games to finally end their last chance of qualifying for the Champions League next season.
The battering by Brighton possibly marked the nadir of an apocalyptic season and the United supporters chanted "You're not fit to wear the shirt" in the second-half.
