Not even close. He used his skin color to single him out instead of using his name. He would've never said that white guy.
But he would have said "the blond guy" or "the bald guy" or "the one with pink hair" (no matter the skin color of the player).
It's just that in certain parts of Europe, where there are no black or Asian people, "the black guy" is really not used in racist connotation. If there are 5 people, one of which is black, and if you ask me to point out which one did it, I'll also say "the black guy" if he's the one I'm asked about and I won't mean it in a racist way.
It's just that the Romanian word for black - "negru" - sounds like the word nigger, which is considered racist. If a Croat said it, he would have said "crnac" and nobody would even know what happened, while the game would continue.
