Aston Villa boss Paul Lambert says he is aware of fan discontent and says his team's remaining Premier League fixtures are "13 cup finals".
Villa have not won in 10 Premier League matches and dropped into the relegation zone after a 2-0 defeat at Hull.
Some fans held up 'Lambert Out' banners, and now the Birmingham Mail has called for the manager's sacking.
Lambert said: "I was aware of [the discontent] months ago. I've told the players, they've got 13 cup finals."
The 45-year-old, who signed a contract extension through until June 2018 on 17 September, has seen his side struggle in front of goal.

|Leighton: "The time came for change months and months ago. The football under Lambert for three years now has been absolutely terrible."Losing to Hull City will not surprise any Aston Villa fan who goes regularly. "It's dross. The best thing for us to do there is to sack the manager who is dragging us down."|
|Trevor: "He's turned good players bad. They're a reasonable squad of players, far better than the others down at the bottom of the table, and he's turned them into bad ones. He plays them out of position."He's absolutely hopeless. He cannot motivate. The man hasn't got a clue."|
Their haul of 12 league goals this season is the lowest total after 25 games in Premier League history.
The team's slump has prompted local newspaper the Birmingham Mail to weigh in against the Villa boss, tweeting a picture of its front page saying that 'Lambert Must Go' with the accompanying hashtag, #lambertout.
"This great club is now on its knees and the Holte End is hurting," reads its editorial. "We can no longer stand by and watch that happen.
"Today the Birmingham Mail makes one simple, stark request to the Aston Villa board: sack the manager."
Lambert, however, says he believes his players have the quality to avoid dropping out of the top flight, where they have been since 1988.
He said: "I know they're more than capable of doing it. There are seven or eight teams in it and we just have to get ourselves out of it.
"We've got to keep battling away and keep our heads up. We're certainly in a fight. You have to keep going and keep being positive.
"I can't describe how we feel as a group. I've said to the lads: 'There are two ways to go - you can meet it head on or you buckle under it. Make sure you don't buckle for your own career.'
"It's the biggest 13 games of their careers coming up."
