Toto says that Russell shouldn't have tried the pass because it was a Mercedes he was passing. In the Sky interview the guys got him to admit that if it were another driver Bottas wouldn't have defended so hard.
The problem here is that even though they are on different teams one guy and one manufacturer controls both drivers. Rather takes away from the racing if a driver can be told what to do by someone other than his team principal.
