Chelsea manager Jose Mourinho's has accused the Stamford Bridge board of refusing to back him in the January transfer window.
Reports have already suggested Mourinho could leave in the summer after a fall-out with owner Roman Abramovich.
And Mourinho said: "I've identified the players that I want but they will not come. It's club reasons and I don't have to tell you why.
"I have asked for players and it's not my choice that no-one is coming."
Mourinho was thought to be keen to bring in a defender and a forward during the transfer window.
But the outspoken boss says if he is unable to bring in any new faces then he will not allow any of his squad to depart.
He added: "The information I have is that nobody is coming and if that's the case then nobody is leaving.
"The only thing I know for sure is that John (Terry) will not play against Wigan on Saturday"
"I expect my squad to be the same at the end of the market as it was at the start."
Mourinho refused to discuss his Stamford Bridge future, only saying: "My position is not important. Chelsea is what is important, not me."
Meanwhile, the Blues have suffered a blow with the news captain John Terry's return to action has been delayed by a sore calf.
The defender was expected to make his return from back surgery against Wigan at the weekend but Mourinho confirmed he will not feature.
The boss said: "John had surgery, he is recovering from that, but he is not ready yet.
"We have a lot of problems, because Ashley Cole and Claude Makelele face suspensions, and I do not see Terry back.
"There is no timescale on John. The only thing I know for sure is that he will not play against Wigan on Saturday.
"I am not a doctor. John is not fit to train with the group. He is not in my collective sessions yet, so he is out for the weekend."
