Lewis takes over Spurs talks with Real Madrid for Bale sale
The Mail on Sunday says Bale's future will be decided in the next 48 hours.
And Lewis will not settle for less than £100million in cash for his star man.
An insider said: "It isn't just Daniel Levy involved now. It is Joe Lewis who is going to be facing Perez at the negotiating table. He wants to meet Perez and resolve the Bale situation.
"The main outstanding issue is one of cash, rather than the question of which player, if any, comes to White Hart Lane from the Bernabeu. The sides are still some way apart."
