The Dutchman has stressed that his hesitance to decide on his future is not about the financial aspect of the deal, and is unhappy with Inter's behaviour
Club president Massimo Moratti urged the Netherlands international earlier this week to make up his mind quickly, but the player has made it clear that he will not be forced into make a rushed decision on his future.
"This is not about the money," Sneijder was quoted as saying by La Gazzetta dello Sport.
"Like every player who could be on the move this window, I have to make a decision by January 31. I do not want to rush anything, and I don't like it how Inter have put pressure on me.
"I am almost being forced to make a rushed decision about my future at a crucial moment in my life. After all that's happened in the past few months, I feel that I do not deserve to be pressured like this."
Sneijder has not featured for Inter since September 2012 after he was frozen out over a contract dispute, and he is widely expected to leave the Giuseppe Meazza side this window.
