David Moyes will make a late decision over whether to include Lamine Kone in his Sunderland side to face Manchester City.
Sunderland have confirmed they will offer Kone - who handed in a transfer request last night - a new contract on September 1, the day after the transfer window closes.
Kone released a statement last night saying he wanted a move over claims the club hadn't offered him a promised new deal.
Moyes accepts there was a verbal understanding between Kone, his representatives and the club's previous regime.
But Moyes - who confirmed he will fine Kone for his comments - said it is not unreasonable for the defender to wait seeing as though he has four-years remaining on a deal he only signed in January.
The 27-year-old centre-back is subject of an £18million bid from Premier League rivals Everton.
Moyes was due to speak to the Ivory Coast international this afternoon to see whether he was in the right frame of mind to face City tomorrow teatime (kick-off 5.30pm).
"We spoke with him and he has a four-year contract and has served six months," said Moyes.
"We spoke with him last night at length - and we had already relayed that to him a week ago - that on September 1 we would give him a new contract.
"Both Martin Bain and myself have only been in the door two weeks, we are trying to add to the squad. We have talked about the injuries and how we are trying to do business. Can we do it on September 1? And we have told him that.
"But for some reason that hasn't seemed to have been accepted, they won't listen to that.
"We have got an offer from Everton and we have told them that as well.
"We are happy to continue negotiations but on the first of September, we feel that would be right.
"He has a four-year contract, it is not as if we are desperate. But by all understandings there was something said to him about a new contract if they stayed up.
"We will definitely honour that if that is correct. It isn't on paper, it was just a verbal. We are happy to honour it and have relayed it to them last night.
"It is disappointing that the day before the game the player comes out and does this. I'm not too sure if it is Lammy doing this but he has put his name to it.
"It gives me a decision to make whether I play him tomorrow or not because of the things he has said today."
Kone was pictured on Merseyside on Monday night, with Moyes expressing his surprise the defender had travelled to the North West given the Everton offer hadn't been accepted.
Moyes added: "I was surprised he turned up in Liverpool in midweek, he was never given permission by us. We have not accepted any offer.
"From that point of view, that is disappointing. If you support Sunderland you have to look at it and say we want people who are going to be committed and he is, he is a really good boy.
"I have found him really good to work with, he smiles everyday and did a great job last year. That is why we are saying even though you have a four-year contract and came six months ago, we will look after you on September 1.
"We don't think that is too unreasonable to ask."
Sunderland face Manchester City tomorrow and Moyes accepts it has overshadowed the build-up.
"These things happen, they have happened at other clubs with quite high profile players. I will see how he is this afternoon and have a talk with him, see how he feels.
"If that is his frame of mind then we wouldn't play him. We need to see how he feels.
"It is disappointing the day before the start of a season we are talking about this.
"I have a few injuries, we have some new players in, exciting young players who will make a difference in the future and they will all probably have to take part tomorrow.
"The last thing they need is a manager whose focus is on something else."
