well for star i wanna say it's not ANYTHING against RVP, not because he scored against us or anything.
but this is for me clean red card.

I personally don't think that this was a deliberate tackle. I wouldn't think RVP would do that against an Arsenal player, so I'm just say that he made a silly mistake and was lucky enough to get away with a yellow. I think Bacary Sagna also helped him out by not getting injured after that tackle. Who knows what would have happened if he did get injured, that I'd think that would be a straight red, but that wasn't the case so I'm gonna say it's a lucky yellow. 

I'm not comparing, I'm stating that if Johnson gets a red card, then so should RVP. That's all I'm saying.

What about Wilshere's tackle on Cleverley?
