CHIEF executive Andy Ambler insists Millwall's directors were left feeling "as unhappy as the fans" by Saturday's 2-0 home defeat to Middlesbrough.
And the board now expects to see the Lions come out fighting against Watford on Boxing Day as they look to make amends for an "unacceptable" performance.
Millwall have now won just two of their last 12 league matches and boss Steve Lomas came under fire from some sections of the crowd after Boro scored their second goal.
But their record at home has been good this campaign – the loss on Saturday was the Lions' first in eight games.
Lomas' side travel to Vicarage Road on Thursday, face Doncaster Rovers three days later before hosting second-placed Leicester City at The Den on New Year's Day.
Ambler said: "The directors are as unhappy as the fans after the unacceptable performance on Saturday because we are all supporters too.
"We will be looking for a response over the Christmas period."
When asked at the weekend whether he feared for his job, Lomas said: "The board are pretty strong people but I can't make decisions for them.
"All I can do is do the job to the best of my ability."
