Points deduction? Fine? Expulsion?

I know it may not sit comfortably with some, but with two people in a critical condition, women and children attacked - then UEFA need to come down very hard.

Yes, it's a mindless minority, it always was, it always is. However, leniency will mean the scenes seen last night will become more and more commonplace.
