Roman Pavlyuchenko is in talks over signing a new contract at Tottenham, according to the Russia striker's agent.
Oleg Artemov claims Spurs are attempting to tie Pavlyuchenko down to a new deal less than a year after he looked certain to leave White Hart Lane.
Birmingham came close to landing the forward in January but could not agree a fee with Tottenham.
Pavlyuchenko, who turns 29 a week today, was also linked with a return to Russia but ended up playing a key role in securing Spurs' highest ever Barclays Premier League finish of fourth.
He has been in and out of Harry Redknapp's side this season but has still scored eight goals in 21 appearances and started last night's 3-3 Champions League draw at FC Twente.
"Redknapp wouldn't sell Pavlyuchenko now," Artemov told Russian newspaper Sovetskiy Sport.
"The same can be said of the chairman (Daniel) Levy.
"Three months ago, Levy suggested Roman sign a new contract on improved terms. We are in negotiations and discussing the details."
Redknapp has already revealed Robbie Keane will be allowed to leave in January and Artemov added: "Keane will most likely be sold and maybe (Peter) Crouch.
"Roman isn't even considering the option of returning to Russia any more.
"He has changed greatly over two-and-a-half years in London and has a different perspective.
"If we extend the contract with Tottenham, Roman will probably never play again in the Russian championship."
