"We could be playing the Red Lion on Tuesday and if we play like today any team will beat us.
"I've been a manager for probably over 500 games now and that is probably the worst performance under my management," the former Oldham, Chesterfield, Plymouth Argyle and Newport County boss said.

"I hope they realise they need to step up big time - if they don't, then there is something wrong with them."
