To clarify the TV issue:
The main issue with tonights game is probably the way Napoli sold (or didn`t sell) the TV rights for their home games outside Italy. EVERY channel oustide Italy has problems to show tonights game. RAI International only managed to get rights in the last moment.
As for ALJazeera : They show the games which they have the rights for. This is the first game they might miss... but hope is not lost. If they don`t start Villareal-BEtis at 2030CET then they might show Juve. Probably they were trying to get rights till the last moment.
Eurosport 2 : FORGET SERIE B on this channel. They had the rights because Sportitalia in Italy (who are 51% owned by the same owners of Eurosport) had the rights. Then many teams decided to sell the rights for outside Italian territory individually... and hence Eurosport 2 couldn`t show those games.... so SPortitalia sold all their rights to SkyItalia with the consequence that neither Sportitalia in Italy nor Eurosport2 have them anymore
