Fairly significant difference in the way they did it though. Players often put their hand(s) on the shoulders and it's not a problem, but Di Maria tapped his back which can (and should) be seen as aggressive.The thing is Di Maria's English isn't good. I still think he shouldn't have sent him off. Funny how Herrera put both hands on the ref yesterday when he got booked and the ref showed some common sense. Mind you it wasn't a yellow anyway. Oliver got it wrong and ruined the game. We still might have lost, but acted a bit too precious
I wish people would stop mentioning the Hart episode as an argument why Di Maria should've been let off - it was a mistake that Oliver didn't deal with it back then, and I'm sure he was told that (and/or figured it out himself) and he learnt from it. That's what you want refs to do, and he's still young. Regarding Fabregas, it looks quite bad, but given the fact that he has his back turned I think he just thought it was a coming together and didn't realise that Fabregas is extending his arms and pushing him the way he is. It should've been dealt with though, because it's not a natural reaction from Fabregas - if he'd done that on a player it'd be a clear foul. Oliver actually does quite well to stay on his feet though!
