International teams would be inferior to club sides if they played... an example is Real Madrid probably the best team in world right now but at International level their players struggled at the World Cup.. teams that are allowed the best from various countries and play together every week will be a lot stronger than ones who don't!...
Arsenal won a trophy and Brazil didn't as well...
Ozil

Easily Brazil. They were clattered by Germany who were eventual champions. Maybe you could argue by Netherlands too. Arsenal get trampled by every big team.
EDIT:
I enjoy this bus parking argument because Chelsea SCORED more goals than Arsenal did last season. So if you cant score OR defend you need to get yourself a new mode of transport
Well at least both don't park the bus.
