Portsmouth are reported to have made an enquiry for Tottenham's Younes Kaboul.
The want-away French stopper has struggled at White Hart Lane following his summer move from Auxerre.
Kaboul, 22, has seen his chances limited under Juande Ramos and he seems set to depart after criticizing the Spaniard.
Now Pompey could offer him a route out of the club and to the South Coast.
Harry Redknapp is looking to bolster his defence and he maintains an interest in Rennes stopper John Mensah.
Rennes are already preparing for Mensah's departure and are said to be looking to land Dynamo Kiev's Pape Diakhate.
