Luka Modric will not face Manchester United on Monday night because "his head's not in the right place", according to Spurs boss Harry Redknapp.
Tottenham have turned down bids of £22m and £27m from Chelsea for the 25-year-old Croatian midfielder.
Modric has hinted he wants to leave White Hart Lane, but Spurs chairman Daniel Levy insists he won't sell at any price.
"He's not playing," said Redknapp. "His head's not in the right place."
The Tottenham manager told talkSPORT: "We need him playing, he's very important to us, so we have to sort it out."
Redknapp believes Chelsea's capture of Valencia midfielder Juan Mata on Sunday for £23.5m will affect the situation.
"I would think that's the end of the Modric deal surely," he said.
"The chairman is away. He's said he (Modric) is not for sale, so that's where we're at with it.
"I think he's made up his mind he's not going to sell him, no matter what the price.
"Luka's got to get on with it now and hopefully have another good season for us.
"Daniel (Levy) said he would like to sit down with Luka in a month or so when it's all died down a bit."
Redknapp confirmed he is still looking to bring more players in before the transfer window closes at the end of the month.
And he hasn't ruled out organising a loan deal for Manchester City striker Emmanuel Adebayor.
"I think we'll make a couple of signings, for sure," he said.
"I saw (City chief executive) Garry Cook and he said there were one or two snags over the money.
"We're not paying all his wages, that's for sure, so I don't know where that one's at just now."
