Defiant Paul Lambert vowed not to "roll over" after Aston Villa fans called for his head at Saturday's 1-0 defeat at Leicester.
Villa were beaten by the resurgent Foxes at the King Power Stadium, and have won just twice in their last 17 Premier League games.
Paul Konchesky's winner sunk the visitors who had Ciaran Clark sent off in injury time, following Matty James' dismissal after the pair clashed.
It was Villa's fourth red card in their last seven outings and came after the visiting fans chanted "We want Lambert out" for a second game in a row.
But with Villa 13th and three points above the drop zone, Lambert insisted he will come out fighting.
He said: "It is a great club and has a great fanbase. You have to take it and come through it. There are only two ways you will go, sink or swim, and I am certainly not going to roll over.
"They pay a lot of money to come and watch and I don't want Aston Villa to keep doing what they are doing.
"I think more importantly it's the game, rather than people aiming things at myself. It's the game and we didn't do enough in the last third."
And Lambert felt Clark left referee Michael Oliver with little choice to dismiss him after he squared up to James following the Leicester man's poor tackle.
He said: "It was a bad challenge initially, Ciaran's run in to help Jores [Okore]. Ciaran has not helped himself as he was on a yellow card. I think the fracas was nothing."
