Follow live updates from Group E as Serbia take on Switzerland.
Switzerland coach Vladimir Petkovic apparently does not want to discuss the issue of tensions linked to Swiss players with Kosovo Albanian heritage ahead of the World Cup match against Serbia.
A reporter asked Petkovic how he would discuss the issue with his players, and the coach sidestepped the question.
Speaking through an interpreter, he says: "We will tell them we had a great match against Brazil. That's not enough; we have to play better against Serbia."
Tensions have been building in Serbia ahead of the Switzerland match. Not between Swiss and Serbian fans, but between Albanian and Serbian supporters.
That is because several players in the Swiss squad have Kosovo Albanian roots, including midfielder Xherdan Shaqiri who was born in Kosovo, the former Serbian province that declared independence in 2008. Serbia does not recognize Kosovo's independence and relations between the two countries remain tense.
All Whites' players now have four months at their various clubs to make their case.
