Manchester United manager David Moyes reportedly has three games to save his job.
The champions have struggled to adapt to life under the Scot this term, and the 3-0 defeat to Liverpool on Sunday was their ninth of a disastrous Premier League campaign that has seen them slip to seventh.
United host Olympiacos in the Champions League on Wednesday looking to turn around a 2-0 deficit from last month's first leg in Greece, and the game is followed up with a visit from fierce local rivals Manchester City after a trip to West Ham United on Saturday.
According to The Sun, Moyes's job rests on the outcome of the three games, and defeat in Europe this week would virtually confirm their absence from next season's Champions League after falling 12 points behind City, who have two games in hand, in fourth place.
Meanwhile, Moyes reportedly held crisis talks with his team after the defeat to Liverpool.
