It makes sense for the Americans to be selling. They have not enjoyed their ownership, and whilst they have managed to reduce their losses by taking profit I suspect they have gone as far as they can with that. It looks like a good time for them to get out. Sooner or later you have to cut your losses on a bad investment. No playoffs this season is the killer I think.
I can see how Rodrigues might be able to make money from running the Swans - essentially find young quality players who are not visible outside Brazil, put them into the Swans for visibility and increase value, then sell their contract into the PL. Might work, but yes this probably just silly season.
