Andrei Arshavin's move to Tottenham is being held up by Zenit St Petersburg's financial demands, according to the player's agent.
Dennis Lachter confirmed Tottenham are in the process of negotiating terms with the 27-year-old, whose impressive performances for Russia at Euro 2008 attracted attention from across Europe.
'At the moment there are negotiations between Arshavin and Tottenham, however, because of the big transfer sum Zenit are asked for, it is taking some time,' Lachter told daily sports newspaper Sovetsky.
'(Tottenham boss) Juande Ramos wants to sign Arshavin and has made him his main transfer target. (Chairman) Daniel Levy is also doing his utmost to make sure the transfer goes through but it is proving difficult to reach an agreement with Zenit.'
Lachter revealed Arshavin had long been a target for Ramos, who even contacted the forward in person to help secure the deal.
'Ramos has been following Arshavin for a long time, even when he was coach of Sevilla,' Lachter continued.
'Andrei has already expressed his desire to move on from Zenit and has also said that he wants to play for Tottenham. He likes the team's style of play and Ramos' style of management.
'Ramos has phoned the player directly and in that conversation he spoke of his vision for the club and the role Arshavin will play in that.'
