It's part of his personality. I'm fine with him being full of grinta, but at least he has to master his emotions otherwise he'll be exposed in every difficult situation. Last night was pretty damn unnecessary to get a yellow card for that, because that was a foul, a very clear one actually, so he didn't had any reason to bitch about it.
What frustrates me, is when he's having a stinker and yet again he bitches about teammates or moans about anything else rather than focus on his own shit.
I still adore him as a footballer. It's been a while since we've had such an elegant player in midfield. Just needs to get his shit together and act like a real man. It's okay to get out of yourself sometimes, but not in a regular basis lol.
