An "embarrassed" Ruben Amorim raised doubts about his Manchester United future after another poor performance from his team in a 2-0 home loss to West Ham on Sunday.
Three days after United reached the Europa League final, they were brought back down to earth by another lowly side in the Hammers, with the London club recording their first top-flight win at Old Trafford since 2007.
Tomas Soucek and Jarrod Bowen scored the visitors' goals as United, once the undisputed kings of English football, suffered a 17th defeat in 36 league games this season to sit 16th.
This latest lacklustre display angered Amorim, who has already given his team several public dressing downs since replacing the sacked Erik ten Hag as United manager in November.
