Bournemouth could be set for a triple capture of Portsmouth youngsters.
Christophe has been training with Kevin Bond's side in pre-season, and his manager has had a good opportunity to analyse his possible capture.
"We had a good look at him for a week or so when he came to us," he told The Echo.
"He's a big, strong boy whose favoured position is central midfielder and if I could tie up something at the right money, I would.
"I don't think Portsmouth would have a problem with us loaning him. I'm hoping the boy would be happy with that as well as he has spent time here already, so it's just a question of seeing if we can get it through at our end."
