I don't think either deserve red cards, that's for sure. Still, regardless of what you're doing, if you do it in front of opposition fans then you're doing it in the wrong place. It's not that hard to run to a different area of the pitch.

I don't think that either of them have done much wrong aside from that little mistake of celebrating in front of opposition fans. However, when a player celebrates a goal in front of home-fans and still gets disciplined - a la Ronaldo (even if he did look like he was trying too hard to look awesome) - then I think it's a bit dumb. Let them have their fun when they score goals, it's good for the game.
