Well, to be fair, we've seen players sent off before for simply touching or slapping an opponent's face. Not first time dy. Fernandinho is just too hot headed and not clever enough to capitalize on it.

If I am Fernandinho, when Fab touch/slap my face, I would've done a Busquet dive and lay on the ground, hands on my head, roll around for 3 min. Then it would've been Fab that got the red card.

Just can say Fab is very sly. But that does not warrant Fernandinho to choke Fab.

2 wrong doesn't make 1 right. Fab was lucky Fernandinho didn't drop to the floor holding his head, and also lucky that Fernandinho reacted more violently, which cause the ref to divert the attention to Fernandinho. Things could have gone totally the opposite way if Fernandinho fell to the grown due to Fab's hand around his face. lol
