There was little sign of fight among the Kilmarnock players and their furious fans took aim at Johnston. They held up a banner reading "AJ out", while chanting that he was out of his depth.
"To be honest with you, that was embarrassing," Johnston said. "A poor performance. That's as frank as I can be. We've got to show more desire. That is unacceptable because our futures are on the line. If we put on performances like that, we're going to get relegated."
Johnston could not hide from the stick he was getting from his own supporters. "Of course you are going to notice those chants.
"But you're the manager - you get the praise when it's going well, you get the stick when it's not. Deservedly so this time, because that's not good enough."
