The Ghanaian midfielder has agreed terms with Pompey and will become the club’s record signing, when he moves from Udinese for £7million.
He said: “I’m just waiting for the day to join Portsmouth. I want to play here.
“To step on this ground, it’s like I’ve started in the Premiership already.
“It’s a fantastic club with class players like Pedro Mendes, Sol Campbell, David James and Kanu and a great manager in Harry Redknapp, who has been following me since last year.
“I’ve been supporting Portsmouth for a year, ever since they said they first wanted me, watching the games. It’s been a fantastic season.
“I spoke to Harry Redknapp before the game. We shook hands and he told me to enjoy it.
“Harry Redknapp’s not just a good manager, he’s a good man.
“I could see that in the changing rooms from the way that he was talking to the players. It was fantastic.
“I know that as a player if I’ve got a problem I’ll be able to go to him.”
