Manchester United lost six games in all competitions in December, only the third month in their history which they have lost that many. They also conceded 18 goals in December, their most in a month since March 1964 (also 18).
Since Amorim's first game in charge on November 24, only Southampton (7) have lost more games in all competitions among Premier League clubs than United.
United will end New Year's Eve in 14th place in the Premier League, their lowest position at the turn of a year in the league since 1989, when they ended that year in 15th, eventually finishing 13th.
United have lost three consecutive home league games for the first time since February 1979, while they have lost three consecutive Premier League games within the same season for the first time since December 2015 under Louis van Gaal.
