If he went to Catalans I'd accept that, he'll probably want to go back and prove himself, he could also potentially make his name as being one of the best French players ever, playing for his hometown club.. not to mention all his family being there..
it's just like St Helens lads wanting to come back here, but probably a bit more, from his social media he's obviously a proud Catalonian..
Finger's crossed we can keep him though, I think Castleford would be a definite step down for him
