Chelsea's important 1-0 home win against Everton came at a price. But, as it turns out, it's not a particularly significant one: the Blues (and the Toffees, but we don't care so much about that) have been fined £30,000 by the FA for failing to control their players in the melee that followed Gareth Barry's red card. And, incidentally, preceded Willian's late goal.
A £30,000 fine is basically inconsequential for a team with Chelsea's resources, so I think we can safely say that nobody will be too stressed out about it. It's just the sort of thing that happens after a big scrum like that, and now we can safely put the whole thing behind us (apart from Everton fans, who are guaranteed to boo the world's most loveable right back when next we meet).
It wouldn't really be a Jose Mourinho season without at least one failure-to-control-players fine, anyway.
