Aitor Karanka revealed he will make changes to the side when Nottingham Forest take to the pitch against Burton Albion on Saturday.
The Reds were disappointing in defeat against Hull City last weekend and Karanka said the reaction from his players has been good in the build-up to the game at the Pirelli Stadium.
He said: "On Sunday when the players came in, the atmosphere was awful after such a defeat; nobody wants to lose games but on Tuesday they went out for training and I knew that they were ready for the challenge. We know that we have to win games, we know we can win games and we just have to do it on the pitch.
"I need to think about my team until Saturday. I have 90-95 per cent the team in my head but I need to have a think. A coach once said that after those kind of games, you want to change 11 players. On Tuesday you want to change six, on Thursday three then the following Saturday you will have the same team.
"But I will change something for sure, as I know that we need to change something. I hope that those changes will be good for the team."
Karanka said that the side must go into every game with a winning mentality, regardless of the opposition to end their bad run of form as they come up against bottom-of-the-table Burton.
"It is better to forget the position in the table as we need to win," he added. "I don't care if it is Burton, Arsenal, Man City or Wolves. We showed that we could compete against Wolves, we showed 10 days ago that we could compete against Fulham but it is about winning games.
"It is about the winning mentality. I prefer to play good football, but if we don't play good football and still win the game, that would be a good scenario.
"We need to start with the winning mentality, we need to approach games thinking that we have to win those games. Football is football, it is impossible to win every single game, but when you have the right mentality it is easier."
