Diddi, Redknapp still owns this house. You may be getting his houses confused. Redknapp did own a home very close to this one in Branksome Park, which he sold to Pompey defender Hermann Hreidarsson.
But do you think he lives there today? I mean it would be difficult to go to the training center everyday and it takes around 2 and a half hour to the training ground by car. So i thougt that he had a house close to that place ( training center).
