Fans again called for Megson to be sacked after Bolton slumped into the bottom two after Saturday's 2-1 defeat at Wolves.
They now face two home games in four days - against Manchester City on Saturday and a relegation six-pointer against West Ham a week tonight.
Megson said: "I don't like criticising my players publicly but three or four of them are not playing like I know they can.
"We've got exceptional players who are not playing as well as I know they can. Our club deserves better than this. We're in trouble.
"With two home games coming up, there has to be a realisation of what we're doing.
"The message is not getting through to a few of the players."
