The Nigerian legend is convinced he can fire the Blues to safety.
Kanu told The News: "I can play a big part for us - if I'm allowed to.
"I'm a Portsmouth player and I don't want the team to go down. I love this team and I love the fans.
"It's going to be difficult, but we have the players. I genuinely believe we are better than a lot of the teams above us. We need points. We have been playing good football without the points coming.
"As a player, I believe if we can keep doing it our luck will change one day."
