Weak management and then publicly taking sides the Mercedes management have only themselves to blame, they shouldn't have left the drivers free to race when there is so much at stake. As for hamilton saying Rosberg has admitted it, I don't believe it, hamilton seems to think he is always the victim and never at fault..
There's nothing at stake. They will win the WCC and one of the drivers will win the WDC, this is a minor inconvenience to them at most.
