Scunthorpe manager Ian Baraclough is hoping to shock his players into life after given them a roasting following Saturday`s 3-0 surrender at Millwall.
The Iron have lost five successive matches in the npower Championship and are gearing up for a fight with relegation.
Baraclough was furious after the performance against the Lions and let his players know his feelings during a post-match inquest.
"What has been said in the dressing room will remain private," said Baraclough.
"There were some harsh words. Hopefully they have been hurt by them because that is not good enough for a Scunthorpe team to perform like that.
"I have not had to question my players' desire in any previous games, but on Saturday we were lacking in that department."
