The former Inter Milan hitman is midway through a one-year deal with Flamengo back in his homeland. But Adriano is braced for a move back to Europe and his agents are sounding out possible destinations.
They are also claiming that a clause in Adriano's contract will allowhim to leave on a free transfer in the January transfer window.
Up for grabs: Adriano wants to return to Europe
Redknapp has previously shown interest in landing the Braziian, who was released earlier this year by Inter boss Jose Mourinho after skipping training to celebrate his birthday.
Adriano is desperate to kill off his reputation as a wild man and restore his reputation as one of Europe's most feared strikers.
Spurs are expected to offload Russia striker Roman Pavyluchenko in January and would be on the hunt for a replacement. They are also understood to be monitoring Club Brugge midfielder Vadis Odjidja.
