Jamie Carragher believes Erik ten Hag is on trial and is effectively an interim coach until the end of the season, following Sir Jim Ratcliffe's takeover.
Ratcliffe's arrival comes in the middle of a poor season for the Red Devils, who are eighth in the Premier League and out of Europe.
Changes in ownership can often lead to upheaval at clubs, and Carragher believes Ten Hag's position is under serious threat unless results improve between now and the end of the campaign.
In his column with the Telegraph, he said: 'Erik ten Hag is on trial as Manchester United manager since the Ineos ‘takeover'.
