Serbia lost 2-0 in a friendly against Spain on Saturday, but 20-year-old Serbian midfielder Adem Ljajic committed an offense before the match even began that would get him kicked off the team.

According to the Football Association of Serbia, Ljajic breached their code of conduct by not singing the national anthem with his teammates prior to kick off due to "personal reasons." Said the FAS in an official statement.

"Coach Mihajlovic yesterday held a meeting with Ljajic. After hearing Ljajic did not sing the anthem due to personal reasons and that that stance would not change, Sinisa Mihajlovic told the player to return home.

As the statement implies, this move probably has more to do with his general attitude than just his willingness to sing the anthem.

Tough few weeks

Four weeks ago, Ljajic goaded then Fiorentina manager Delio Rossi after being subbed out of a Serie A match in the first half. Rossi responded by physically attacking him in the dugout.
