Nottingham Forest manager Billy Davies admits he has a big decision to make over whether to start Radoslaw Majewski in the play-offs.
Majewski has enjoyed an impressive season on loan at Forest from Polonia Warsaw and is eligible to feature in the play-offs next month.
Forest are trying to secure the midfielder on a permanent contract, but several weeks of talks have failed to bring an agreement to keep the 23-year-old at the City Ground.
Davies accepts Majewski may be a key player for Forest in the push for a place in the Premier League, but he is also concerned about the impact an uncertain future could have on the player.
"As far as I am aware the deal does allow him to play," said Davies. "I am not aware of there being any other situation, but I will pick whatever side I have available.
"He might be a key player for us and he might not be. He might not be a key player if we do not sort his contract out.
"I need to start preparing for a situation where we might not have Raddy. I am not only looking at fitness and form, I am looking at the mental side of things.
"It is time to understand that, when you get to the play-offs, it is not just another league match, it is time for another mentality. It is time for mental strength to come to the fore."
