A Spain star Diego Costa has started greatly for his country at the World Cup 2018. Thanks to his goal at the Kazan Arena on Wednesday Spain managed to beat Iran. But after the match Iranian defender accused Costa of insulting his mother and sister during the match. 

“Diego Costa cussed everyone in my life during the entire game. The things he said to me from the start till he went off were disgusting. He constantly insulted my entire family. He would just turn around and look me in the eye and insult my sister and mother”, said Morteza. 

There is no doubt that Costa is a fantastic player but saying such things about someone's family he crosses the line.
