Leeds boss Neil Warnock said: "I shall see how Luciano looks in training and make sure his head's right in the next 24 hours before deciding whether to chuck him in against Spurs.
"If I'm honest, I have to say his mind has not been on his business over the last few weeks.
"But he is a good pro who always gives 100 per cent on the pitch - and I expect that to continue for as long as he remains at this club. I am not pleased about this situation with Luciano.
"It has been bubbling below the surface for a while now, and you can never be happy when offers come in for your best players.
"We have tried to settle Luciano down by holding talks over a new 3½-year deal for him.
"We have put a Premier League-size contract on the table - certainly the biggest I have known in my time as manager here - but he just doesn't want to know.
"That is his prerogative and all he is looking to do is get security for him and his family.
"But he has got 18 months left on contract here and he won't be going anywhere unless someone comes up with the money we think he is worth.
"If that doesn't happen by Thursday then he'll just have to knuckle down and get on with it here. We don't have to sell."
