Well you definetely seem to be.
Why the feck shouldn't he answer to opposition fans like that? There was nothing wrong when Mourinho did it to Juventus fans and there is nothing wrong now.
I can't get my head around the fact that some people actually think it's because of jealousy. I really can't.
Did you ever stop to think that some people get more flak than others because they weren't blessed with a likable personality or demeanor? He's vain, confident to the point (well beyond it) of arrogance, and extremely sore loser. Some people are just easy to dislike, Ronaldo, Mourinho, Neymar, Griezman, Memphis, Robben. I mean, I'm a big fan of Arjen Robben, but I don't for a second think so many people think he's a twat because they're jealous. He's simply a whiny cnut sometimes and if you have no vested interest in him doing well, chances are you won't like him.
Ronaldo doesn't have to do anything, he can react to those fans in whichever way he wants. For all I care he moons the crowd and reveals a tattoo of Simeone being bummed by a gang of leprechauns in Juve shirts. That's beside the point. He's just a bit of a tit. He's also however, extremely good and if you support his team or his country, why would you care.
And on the note of booing, aren't atletico and Real rivals? And didn't Ronaldo do quite okay for Real?
