French defender Younes Kaboul looks set to leave Spurs on Monday and join Portsmouth.
A Portsmouth spokesman said: “We agreed personal terms on Friday and if all goes well he will sign on Monday,”
Pompey coach Joe Jordan added: “He’s a player who’s the right age and who we’ll need.
“He’s made a commitment to Portsmouth and he’ll be a very good acquisition.
“He’s at the right age, he’ll learn from playing alongside Sol Campbell. He’ll gain that experience that all players need and hopefully he’ll be the player we’re looking for.”
