Tottenham are eyeing Portsmouth midfielder Sulley Muntari.
Fratton Park chief Harry Redknapp tried to sign Kaboul in January and Spurs are willing to use the Frenchman as bait for Muntari, with £7million in cash on top.
Redknapp will be desperate to keep Muntari, 23, a £7m signing from Italian club Udinese last summer. Pompey now value him at double that fee after an outstanding debut season in England.
