If it isn't in the managers plans then he should toe them in the baws and get them in line - If he can't get them to carry out his instructions then he isn't up to the job and should be punted.
I could understand people saying that its the players fault for not listening to their managers instructions if it was only a one off game but every week we're going on to the park and committing the same mistakes time and time again. I think Baraclough has a decent (and only decent) eye for a player but for me he doesn't look like a manager. Terrible substitutions and poor tactics aren't down to the players.
Alarm bells started ringing for me after seeing Anthony Strakers debut. Not because of his performance per se, but because of how Baraclough had talked him up pre-match as someone who was a good crosser of the ball, equally comfortable at left back of left midfield. Since then it's been the same pre match cliches about the positives, "doing the right things in training" and how confident we are before we're handed the inevitable pumping. In his post match interviews he stands there sweating his box in speaking with all the confidence of a dug chasing its own fart. I think he knows he's out of his depth.
