Cardiff City boss Ole Gunnar Solskjaer has shelved plans to take his players for warm-weather training following Saturday's 4-0 home defeat by Hull.
The Bluebirds were due to fly out to Abu Dhabi on Sunday, but Solskjaer now wants his players to stay in Wales and prepare for next Sunday's Premier League trip to Tottenham.
Defeat by Hull left Cardiff three points from safety in 19th place.
"We've just got to work hard," said Solskjaer.
"It's not going to be easy to go to Spurs next Sunday.
"We have an extra day to prepare for that game and we are going to be prepared."
Solskjaer had targeted Saturday's game against Hull as a potential win for his struggling side.
"We're very disappointed. Not good enough in front of both goals, defending and attacking," he said.
"It's a real awakener. We wanted to catch and be just two points behind them [Hull]. Now we've probably lost contact with them for a while."
Cardiff had started brightly, dominating possession and creating chances, but Steve Bruce's side were more clinical in front of goal.
A brace from Nikica Jelavic and goals by Tom Huddlestone and Jake Livermore gave Bruce his 100th Premier League win as a manager.
Solskjaer says Cardiff now need five wins from their last 11 matches to survive.
Since replacing Malky Mackay in January, the Norwegian has won only one of seven Premier League matches, and admits the fight to maintain Cardiff's top-flight status is the biggest test of his career.
"It is because it's a different challenge," said Solskjaer.
"When you get disappointment as a player you go into work the next day and you do your best to prove [you're good enough] to the manager.
"Now I'm the manager and I look at whoever wants to be part of this team and who's going to help us out of this situation we are in."
As a player, Solskjaer was part of a Manchester United team famed for never giving up, typified when he scored the second of two stoppage-time goals to help the Red Devils come from behind to win the Champions League in 1999.
That "never say die" Old Trafford mentality is something the Norwegian says he still possesses, and that it applies to the situation Cardiff currently find themselves in.
"I'm never going to quit," said Solskjaer. "I'm going to be in front of these lads and guide them and lead them.
"I've got to take them somewhere they've probably never been before as in mentality and mindsets.
"It takes a lot out of players losing games like this. They're disappointed in there but it's my job to get them going again and win the five games we need."
