Peterborough`s underperforming players have been denied a day of rest by manager Gary Johnson after their 5-1 home hammering at the hands of Charlton.
Posh were four goals down by half-time at London Road and Johnson will make his side watch a re-run of the horror show on Sunday in a bid to show where it all went wrong.
Speaking after Saturday`s humiliating loss, he said: "I threw on three substitutes at half-time to try and change our mental state and we looked a little bit more like our normal selves from then on, but by that point it was way too late.
"The players will be in on Sunday to watch the video and see for themselves where they went wrong.
"But while we were bad, you have to admit that Charlton were very good. They capitalised on our performance and any mistakes we made."
