Sorry but if you know anything about twitter and the aftermath of a big game, then you know all the racists and trolls target the losing teams black players. So when 3 black players miss penalties in the Euros final, it is bound to be a s***show! Unfortunately it's just the current state of play. But you want to criticise when he made a comment that has proved 100 percent correct.
I find it insulting, because that is the the head in the sand behaviour that allows that crap to continue. People are free to say what they want, so long as their racism doesn't manifest in the physical. And yes the we show be thick skinned and ignore the idiots. But people with racist views are at the very least ignorant, and people that say the racist abuse isn't that bad, or deny it are ignorant at the very least also.
