Zenit St Petersburg have warned Arsenal that they will not lower their valuation of star forward Andrei Arshavin just to get a deal done this month.
The 27-year-old playmaker is adamant that he wants to leave the Russian club, but Zenit continue to play hardball with the Gunners and any other potential bidders.
Zenit's general director, Maxim Mitrofanov, confirmed: "The situation has not changed since Friday, which means Arsenal would like to pay only £12million, not one cent more.
"We at Zenit are ready to discuss with them about maybe a better offer from our side. We are ready to make a step forward to them, but they should do the same.
"However, I have told the people from Arsenal we are ready to discuss a lot of things to make the situation easier for them.
"They have a deadline, as I understand, until January 26, because after that, they should have some time to get another player and I respect this position."
Arshavin has been linked with a number of top clubs across Europe since starring for Russia at last year's European Championship finals.
Real Madrid, Barcelona, Juventus and Internazionale have all previously been credited with an interest in the talented left-footer.
