West Ham United must win at least one of the relegation-threatened club's next three games or manager Avram Grant will be sacked, BBC Sport understands. Time is running out for the 55 year-old Israeli, who has just one win in 11 matches, with the club three points adrift at the bottom of the table,
West Ham play Blackburn Rovers away on Saturday, then Fulham away on Boxing Day before meeting Everton.
A source said this allows the club to make best use of the transfer window.
"If we didn't win once by the turn of the year then there would have to be a change before the start of the January transfer window to give a new manager a chance to make the changes he wanted," the senior source told BBC Sport.
