Steve McClaren will haul his embattled Newcastle squad in for an extra training session on Sunday following their humiliating defeat at Crystal Palace.
While Palace's triumphant players headed off for their Christmas party on Saturday night, Newcastle's day off was cancelled in the wake of the 5-1 defeat.
Newcastle boss McClaren insisted he was right to tear into his players in midweek following the 3-0 home loss to Leicester City, despite receiving another thumping at Selhurst Park.
The former England manager expects to lose the fans' backing after a seventh loss in Newcastle's last 11 league matches cemented their relegation battle.
"I said to the players 'back to work tomorrow morning'," McClaren said, after Yannick Bolasie and James McArthur both bagged goal braces in south London.
"These players have got to come through this, but there's no one more determined than myself to do that, starting tomorrow morning. We hadn't planned the extra session.
"It's not right. We need to sort it out. You're going to do that on the training field, within the group, and within the work, and we've got to come through together.
"I'm hurting as much for the fans as ourselves. I'm really hurting.
"I've hurt in the past and we knew this was a tough job but this is getting tougher by the weeks.
"We know we're in a relegation battle, we've got 24 games left.
"It's about coming through adversity and bad times, getting stronger, showing character.
"And character, mental determination and fight - that's what you learn through adversity."
Newcastle took the lead through Papiss Cisse's header, but collective heads dropped after McArthur's deflected equaliser.
Palace raced into a 3-1 half-time lead and quickly killed the game after the break, leaving former Newcastle boss Alan Pardew inwardly delighted to put one over his former club - if outwardly keen not to crow.
While the home side headed out for some festive high-jinx at the Christmas do, Newcastle started the long trudge back to the north east, with McClaren candid about the club's plight.
Asked if he still had the Newcastle fans' support after another drubbing, he said: "Well, I can understand that after today probably not.
"They showed their frustration, disappointment and anger, and rightly so.
"But we're as disappointed, hurt and angry as them."
McClaren called out several Newcastle players for underperforming in mid-week bust-ups at the club's training ground.
The ex-Middlesbrough boss insists he was right to lose his temper and that his squad took his words on board, even in the wake of leaking five goals on the road.
"I definitely know we got a reaction from the players," McClaren said. "The focus was there from the start of the game, the intent.
"But at the present moment when we get a setback we're not recovering quickly enough.
"It's definitely not ability, it's about doing the basics. It's tough, it might get tougher, but we're up for the fight."
Palace boss Pardew hailed his side for a "pivotal" victory that allows the chance to chase a top-eight Premier League finish.
The ex-Newcastle boss offered support to McClaren's Tyneside plight, but refused to be drawn on the St James' Park situation.
"They deserve their night out tonight," Pardew said, sending Palace's players off to their Christmas celebrations.
"They deserve the success, so I hope they enjoy themselves and then re-focus.
"There's no extra satisfaction (in beating Newcastle).
"It's difficult to talk about the opposition, I love the staff and players who are there, and the fans.
"Whatever I say about that club it gets contrived. All I would say is I hope their fortunes improve going forward.
"Our players were really on it today - it was a pivotal game, whoever the opposition was, in our season.
"Were we going to become a mid-table team or were we going to put ourselves back in contention?
"And we've put ourselves back in among the Evertons and the Tottenhams."
