The Belgian international had been linked with a move to Tottenham Hotspur in the last few days.
Any hopes of a deadline day capture have now been dashed with the talented midfielder’s latest interview.
"It is now certain that I will stay at Zenit until January," Witsel told RTBF.
“Then we'll see. If my transfer does not happen, it is not for a financial reason or because the offers received did not interest me… It was important for Zenit to keep me for now.”
It is believed that Zenit’s failure to secure a replacement was the reason they refused to sanction his sale and while Witsel pledged to remain focused, his tone suggests a January exit is on the cards.
He added: “I repeat, everyone will see what happens in January. I'm not disappointed to stay at Zenit, not at all. In my head, everything was very clear. Staying Zenit does not pose any problem to me. I'll stay focused as I always was.
“There had offers from Italy, but even if we had offered 60 million euros Zenit, they would have refused the transaction.”
His revelations will come as a bitter blow to Mauricio Pochettino as he attempts to inject a bit of deadline day magic into the squad.
Two key areas – central midfield and centre-forward – are yet to be addressed and with just a few hours left before the close of the window, any deal coming to fruition is looking unlikely.
The London Evening Standard report that Spurs remain hopeful of clinching a deal for West Bromwich Albion striker Saido Berahino but as has been the case for the last few weeks, his price may yet prove a sticking point.
