He receives abuse for GETTING headbutted?
I mean, he made a meal of it, im sure, as all football players do these days. But its Nunez who should be getting the abuse, if you headbutt someone on the pitch these days, however softly, the players are gonna drop like a sack of **** and writhe in pain ala Willem Defoe in Platoon with the adagio for strings music playing in the background.
That's just a reality of the modern game!
Dont touch players faces with your hands, elbows or forehead and you cant open yourself up to it, simple
