Alan Pardew steamed into his Newcastle United players after their defeat at Sunderland on Sunday.
The Evening Chronicle says Pardew is understood to have torn into some of his players at the Stadium of Light after they lost their second Tyne-Wear derby in a row.
A dressing room inquest is believed to have swiftly followed the 2-1 loss on Wearside - after some players left the travelling Toon Army disappointed by departing the field quickly without acknowledging the fans.
After Pardew's rant, one senior player is also thought to have stood up and told some of his team-mates that there were too many players that were playing for "individual glory" on the day.
A source said: "There was some shouting from the manager afterwards.
"It boiled down to the fact that there weren't enough crosses going in for the front men.
"And there was emphasis on why Newcastle seemed to be lacking in general team play."
