KALININGRAD, Russia — Serbia will attempt to wrap up qualification to the World Cup knockout rounds Friday as it takes on a Switzerland team brimming with confidence after grabbing a draw with Brazil.

The Serbs control their own destiny in Group E after an opening 1-0 win against Costa Rica Sunday, which came courtesy of a stunning Aleksandar Kolarov freekick.

Victory over Switzerland in Kaliningrad Friday would guarantee Serbia a place in the last 16, regardless of whether it win or lose its final group game with Brazil next week.

Roma star Kolarov acknowledged that Serbia is in a strong position to qualify for the knockout rounds for the first time since it competed alongside Montenegro in 1998.

However the 32-year-old cautioned that the Serbs would take nothing for granted against the Swiss.

“It’s very important that we have these three points in the bag, but it’s not over, Switzerland will be the hardest match,” he said.

“I don’t want to do the maths for now, if we draw it would not work, we want to win of course.”

Serbia boasts a host of current and former Premier League talent, including Manchester United Midfielder Nemanja Matic.

But its rising star is Lazio’s Sergej Milinkovic-Savic, a rangy attacking midfielder who has drawn comparisons to Serbian great Dejan Stankovic.

Former coach Slavoljub Muslin, who led the team to qualification for Russia, reportedly paid with his job for failing to select Milinkovic-Savic.

It’s not a mistake current coach Mladen Krstajic intends to repeat and the Lazio man — who has reportedly attracted the interest of Real Madrid — was lively against Costa Rica.

“Milinkovic-Savic is a great player, with really exceptional technique,” said Swiss defender Denis Zakaria.

“It’s not just him, lots of their players play for big clubs, but we also have good players.”

Switzerland was ranked above France and Spain in sixth place before the tournament and battled hard for a point against a Brazil side led by Neymar in their opener.

“It was very good teamwork on the right side. It was almost a perfect game. It’s important to have this teamwork,” said Arsenal-bound captain Stephan Lichtsteiner.

Serbia has based itself in Kaliningrad — Russia’s European territory on the Baltic Sea — throughout its stay in the tournament and tens of thousands of its countrymen are expected to travel for the game.

One sub-plot to watch for could be the Serbian fans’ treatment of Switzerland’s three Kosovan-born players.

Midfielders Valon Behrami of Italian club Udinese, Arsenal’s Granit Xhaka and Xherdan Shaqiri of Stoke City were all born in Kosovo and all three played in the Brazil game.

Kosovo was a former province of Serbia, and Serbian fans gathered in Kaliningrad Tuesday night to celebrate Russia’s 3-1 over Egypt while chanting “Kosovo is Serbia.” — Reuters
