The story i've had on ikahifo is that Germ wasn't impressed with his fitness levels and told him if he wanted to stay with him and the club he needed to sort it out, he hasn't done enough so germ stood his ground and told him he was offering him around as he didn't do as asked, it seems a deal can't be done so for now he's staying but unless he bucks up he won't be playing much.
Dunno how much truth there is in it though as i can't say i ever really noticed any fitness problems but i guess that's why the coaches know best.
