Sunderland players have been subjected to a video horror show by furious boss Ricky Sbragia.
The manager is still reeling from his side's dreadful performance at West Bromwich Albion on Saturday.
The 3-0 defeat, which has given West Brom their own hopes of survival, has left Sunderland in the thick of the relegation battle and with Everton to face at the Stadium of Light this weekend, Sbragia has delivered a harsh warning to his players at their training ground.
The Sunderland boss said: 'I hope to see a completely different Sunderland side against Everton because that's what the fans deserve. The one thing we should always be guaranteed them is commitment.'
Sunderland chairman Niall Quinn was also unhappy with his players' performances at The Hawthorns and has pleaded with them to raise their game for the last four matches.
Quinn said: 'We had a very poor game on Saturday and the fans went home very very unhappy.
'They know what they have to do next Sunday at home to Everton. They have to rev the engines up and get going.
'Sunderland fans want one thing - genuine passion. They will forgive just about everything, I saw them clap their manager at Maine Road many years ago when they got relegated.
'They just want to see their team give genuine effort, genuine passion until they drop. I genuinely believe that if the work-rate is good if we are passionate and making our tackles and with the Sunderland crowd behind us the players will be fine.'
