Probably but maybe there's a day or 2 embargo - surely the club are told before Sky tell the world... Just playing devils advocate, if the OP is telling the truth then the club will either know or they shouldn't be telling fans anything '100%'...
Has anybody thought maybe the club have heard what the Sky picks are (before it's released publically) and therefore CAN confirm 100% it's on the Saturday? After all the Friday rumours were started before Sky have confirmed anything...?
