Nemanja Matic was furious with his Serbian teammates following their 4-1 defeat to the Czech Republic.

"I always try to lead by example but some people don't want to see that,"Matice told reporters.

"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.

"I told our coach [Radovan Curcic] there is no point in me carrying on with the national team if things don't change."
