Nottingham Forest boss Billy Davies has revealed that he dropped Radoslaw Majewski because the Pole is becoming unsettled over his future.
The young midfielder has shone for Forest this term, after signing on loan from Polonia Warsaw.
Davies has been pleading with his club's board to make the deal permanent, but as yet nothing has been agreed.
Davies then decided to leave Majewski out of his side at the weekend, because he says he was not focused.
"I am worried about the lad, because his head is away. He is very concerned about the lack of contract negotiation," said Davies.
"I have said before that we have to get him tied up as soon as possible and it seems to be taking a bit of time.
"It is now affecting him. Having watched him in training and spoken to him, I am left trying to keep his head up and convince him that he is part of this club.
"But, at the moment, he is beginning to question what his long-term future is.
"I have said that the player should be signed, that he should be part of our future going forwards. But the negotiations are dragging out.
"These things do not help the players and the team. We have to get things tied up quickly.
"We have to allow people to settle in and know that they are here for the long haul. We have to remove any negatives that float around inside their heads.
"The player wants to stay and I definitely want him to stay. I am not sure where we are in terms of negotiation. All I do know is that we had to drop a player that helps us with our passing and play.
"I felt it was right to take him out because of the frame of mind he was in. We can't allow the situation to continue."
Davies has already hit out at the club's failure to sign any new players in January, and he remains upset.
"I am disappointed in the lack of activity (in January), I am disappointed that I have to play a right-footed player, in James Perch, at left-back," he said.
"I have a midfield player in Chris Cohen, who I have to persuade to play at left-back in the future now," he said.
"And, I'll be honest, I am having a bit of a tough time with it, because the lad is enjoying playing in midfield. I might have to force him to do something he is not keen on.
"It is affecting our passing game, because of having key players missing and in the wrong positions.
"You see the reaction you get from new faces - look at Newcastle's result on Friday night. You can see what new faces do for a team. Additions give you a lift. It is crucial to understand that.
"I am concerned because we have to fit round pegs in round holes, not doing that is affecting the way that we can play.
"We cannot afford to have square pegs in round holes. We cannot afford to have influential players questioning whether they are an important part of the team.
"I know players, I know how they think. We need them on our side and feeling part of things."
