Nottingham Forest manager Mark Warburton is hoping his side can give a positive reaction when they take on Sunderland at The City Ground on Saturday.
The Reds suffered a disappointing 3-0 defeat against Sheffield Wednesday on Boxing Day and Warburton hopes his side can bounce back with a result and good performance against The Black Cats.
He said: "We've been back in, training this morning and you have to have honest conversations as players and staff.
"We let a packed City Ground down on Boxing Day. It was tough to lose 3-0 at home and we hope it never happens again. We have to look at it and we can talk about missed chances, a wonder goal and penalty decisions, but it is irrelevant. The fact is we lost the game 3-0 and now we have to look at our reaction.
"We have to demand better and work harder, simple as that.
"The young players will learn from it. You can't replicate that situation; we have to see if they are better next time, if they can respond and rise to the challenge and you hope very much that they can do."
Warburton recognises that Chris Coleman has taken on a big task at Sunderland as they have struggled so far this season, but the Forest boss knows his side must focus on their own performance first and foremost.
"Chris Coleman has gone in and recognised the challenge," he added. "They have had a tough start to the season but it is a huge club. They have a Premier League set up and I am sure Chris can see the fantastic opportunity.
"They have had some turnaround results recently but have had some injuries so we don't really know what side we will face. There is talk of six or seven of their players being injured; we will have to wait and see.
"We will respect them, analyse them as best we can but it has to be about us. We are at home and we have to focus on Forest."
