IAN Holloway has vowed he will not "slam the door" in Scott McDonald's face after holding talks with the striker about his Millwall future this week.
McDonald was left out of the Lions' 1-1 draw with Sheffield Wednesday on Tuesday and it is understood the Australian has not trained at all so far this week.
Holloway admits it is possible that the 30-year-old could leave The Den before the close of the January transfer window, but says he will not force him out.
And the Millwall boss insists McDonald could still have a future in SE16.
"Scott and I have had some discussions," Holloway said. "He needs to deal with how he feels and where he is in his mind.
"I haven't got any issue with him, we're getting on fantastically well. I don't do confrontation because you never know what is going to happen. I never say never to anyone.
"But I've told him how I feel and I went without him on Tuesday night.
"If that helps him to do what I want, then there is no problem between us and I will have no issue with welcoming him back to the fold.
"But if he does what he thinks is right, and not what I think is right, then he won't be here, it is as simple as that."
McDonald's agent has been exploring possible destinations for his client ahead of Friday's 11pm deadline for transfers, with a shock move to China one option under consideration.
But Holloway said: "When you have someone who's got 18 months to go on their contract, and not just six months, it's very difficult to move them.
"But do I want to move someone who is capable of scoring a lot of goals when it's surely my job to cheer him up and make him happier?
"I think it is respectful to be straight with someone and tell them exactly what you want, what you don't like and what you want him to think about.
"I will never slam the door in anyone's face. I hear lots of managers say so-and-so will never play for them again, but that's not me.
"Why cut your nose off to spite your face? It's ridiculous.
"I've chosen not to play Scott or involve him. I've asked him to think about a few things. Me and him will be revisiting that and he'll either be playing for me again or for someone else.
"I can't tell you which way that's going to go yet."
