You said lunged into him with his head though. That's another and more intentional wording. Of course that warrants green smilies. Clearly it's not as intentional as you want to make it - he doesn't have his eyes on Neymar - a lunge with the head is like the rememberable Phil Jones head-tackle.
Stop being offended and look at the fact that almost everyone in here agrees that this was questionable. Even the Ref didnt blow it the first time, who had a perfect sight of the situation. So clearly he didn't "lunge" into him - then the Ref would've probably have blown the first time.
He does though, watch the video. He initially falls and then throws his body in front of Neymar, whether or not he had control doesn't matter, it was still done. I'm not arguing whether or not he saw it. You're going in circles, talking about whether or not he saw Neymar, that's irrelevant, he obstructed Neymar's path after making a mistake, simple as.
