Spurs remain defiant over Berbatov, who is desperate to join Man Utd
Dimitar Berbatov's agent is in London for crisis talks as the player attempts to force a move to Manchester United from Tottenham, BBC Sport understands.
Emil Danchev hopes to meet boss Juande Ramos and chairman Daniel Levy in a bid to thrash out the striker's future.
Berbatov was left out of Saturday's loss to Sunderland due to a "lack of focus", while his relationship with his team-mates appears to have broken down.
However, Spurs insist the 28-year-old will not leave for less than £30m.
The London club are threatening to let Berbatov "rot in the reserves", according to reports, rather than sell him for less than they believe he is worth.
That is despite the fact that the situation has clearly unsettled the club, with defeats to Middlesbrough and Sunderland erasing early-season optimism from fans, and reports of a training ground bust-up involving the Bulgarian adding to pressure on the club.
But Tottenham's position has been made more difficult by the fact that no offer is currently on the table for the striker, despite interest from United as well as two Spanish clubs.
At the same time, Spurs' complaint to the Premier League regarding United's conduct in their pursuit of Berbatov is on hold.
Premier League spokesman Dan Johnson confirmed to BBC Sport that the board met 10 days ago to discuss the matter, only to request more information from both clubs. That, as yet, has not been forthcoming.
In the meantime, Spurs are continuing with their efforts to strengthen the squad, with Spartak Moscow's Roman Pavlyuchenko believed to be closing on a move to White Hart Lane.
The Russia striker, who impressed during Euro 2008 with three goals, reportedly met Spurs officials last month and the club could now push through a deal by Friday.
A busy transfer window has seen Tottenham already pay out more than £43m for the likes of David Bentley, Luka Modric, Heurelho Gomes and Giovani dos Santos.
However, the sales of Robbie Keane, Pascal Chimbonda, Younes Kaboul and Paul Robinson, among others, mean they have recouped more than they have spent this summer and are therefore adamant that purchases are by no means dependent on Berbatov's exit.
So, while Andrei Arshavin's proposed switch from Zenit St Petersburg looks highly unlikely, Spurs look certain bring in new faces before the transfer window shuts on Monday.
Ajax striker Klaas-Jan Huntelaar, Radamel Falcao of River Plate and Manchester City defender Vedrun Corluka are also thought to be on their list of targets.
