According to a poster on a Plymouth Argyle fans forum, the proposed bid for Okazaki is rubbish. From the mouth of the Pilgrims' manager himself, it's not going to happen.
Kinda nice that Okachan's name is being bandied about abroad, though. When a serious bid from a team worth considering comes in I'll be the first to wish him all the best, but first things first: the 2010 J. League championship. :)
