"It's getting hard", said Pardew.
But the under-fire boss said he would not resign. "My pride on the side line is such that I don't want to stand there and for that last 15, 20 minutes and watch that".
"I would keep Alan Pardew because they aren't going to get out of it".
"But the one thing I'm not going to do is lay down tools". We lost out shape and we lost our spirit to a degree and that is something that I've only experienced once before here, in the Huddersfield game when our spirit and our confidence just hit the floor, and that is a worry.
"They've got to fight to the end".
The Baggies will definitely be without James Morrison, Daniel Sturridge, Gareth Barry and Nacer Chadli, the opening scorer last time these teams met. Foxes transfer target Johnny Evans is also a doubt, along with Chris Brunt.
During his post-match press conference, Pardew chose not to be magnanimous as he tore into his players, accusing them of giving up towards the end of the game. I don't care whatever job or workplace you're in, if you're under pressure and you don't want to fight, don't bother turning up.More news: Cranberries to release new album, 25th anniversary reissue

The Frenchman said: "It was a good opportunity, a fantastic goal, it's a second goal he's scored with his quality".
After holding off the Leicester attack for around half of the match, the Baggies eventually crumbled as some good interplay between Iheanacho and Mahrez led to an intricate pass from the Nigerian leaving Mahrez with the task of chipping Ben Foster which he did easily.
"We are happy to win the game, but it's not just the result but the quality we can put onto the pitch".
On-loan Chelsea winger Kennedy bagged a first-half brace before Matt Ritchie sealed the win in the 57th minute.
"It wasn't to be and when their second goal went in which was the most disappointing part of the game".
