Well, perhaps come season's end, when he re-signs with the Dees, he plans to make up the shortfall between the club's offer and the GWS offer, by suing the pants off a few journos
Then again, maybe insinuation (which is what it is... no journo has come out and said "he's lying") is a much harder thing to qualify and prove in terms of legal action.
Yes, he is probably hurt by the insinuations (although I suspect that Schwab may well be exaggerating for the benefit of the press), but there is every possibility he may have a thicker skin than you or I and is prepared to live with those insinuations in the knowledge that he will have the last laugh and that a lot of "highly respected" journos and their "immaculate sources", will be left wiping massive amounts of egg off their faces.
