West Ham’s latest nosedive left Sam Allardyce facing growing unrest from fans ahead of a crunch meeting with the club’s owners.

The Hammers' boss had to endure chants of, “F*** off Sam Allardyce” and, “You don’t know what you are doing” from the travelling fans as they watched their team lose 1-0 at West Brom on Saturday.

They also passed around a banner reading: “FAT SAM OUT, KILLING WHUFC”.

The latest supporter unrest combined with a fourth successive defeat has turned up the heat on Allardyce.

Irons co-owner David Sullivan said as he left the ground: “I’m not saying anything now. We’ll discuss it at the end of the season as we always do.”

Allardyce, who has another year on his contract, has had preliminary talks over a summer budget. But the grumbles over his team’s direct style of play could turn into open revolt if there are further defeats in the last two games, against Spurs and Manchester City.

Sullivan and co-owner David Gold plan to assess his future in end-of-season talks. They feel a home win over Spurs on Saturday would appease fans as it would mean a record third win in a season over their bitter rivals.

The board understand supporters’ frustrations and have noted how moans from the terraces helped push David Moyes towards the Old Trafford exit. But Mirror Sport understands Sullivan and Gold feel Allardyce has fulfilled the brief they gave him, which was to take the club up, keep them up last season and again this.
