The deal to show all games was only agreed because no crowds were allowed in. Next season will go back to normal in terms of TV coverage even if capacity is reduced. You can see this from the first month of fixturesIf the government decide to carry on with restricted (25% to 50%) crowds - which I suspect they will until at least October this year - we should expect to see the same level of TV coverage. That being the case, the fixtures will be all over the shop!
I can't see any 'first choice' players making a trip to Barcelona for a glorified training session.
