Dubé is one of the most credible pundits in Quebec. The fact that he's coming forward with this, has legs. He's not one to engage in random speculation.
I agree that he's credible, no way Dubé sticks his neck out like that without some concrete information. I just have my doubts as nothing ever leaks. Time will tell for sure.
Moreover, if there is any truth to this, then both clubs must already have an agreement in place.
