Nemanja Matic is on the verge of quitting the Serbia team after slamming the “unacceptable” attitude of his international team-mates.

The Chelsea midfielder was so disheartened by last night’s 4-1 drubbing at the hands of the Czech Republic that he has threatened to walk out on the national side.

“I told our coach (Radovan Curcic) there is no point in me carrying on with the national team if things don’t change,” Matic told Serbian media today. “I always try to lead by example but some people don’t want to see that.

“The attitude of some players is unacceptable, not just on the pitch but off it too and it was obvious from the moment we got together on Monday.”

Serbia failed to qualify for Euro 2016 after an awful campaign, which came after they missed out on the 2014 World Cup and Euro 2012.

Matic cited Serbia’s futile 2-0 win at bitter Balkan rivals Albania in their penultimate Euro 2016 qualifier, when they had already lost any hope of reaching the tournament, as an example of how they should move forward.

“When our personal reputations were on the line we did everything right,” said Matic who has played 26 times for his country.

“But I’d really like to know whether some of my team mates apply the same poor working ethic at their clubs as they do in the national team most of the time.”
