Croatia head coach Niko Kovac has banned all player agents from the team hotel as reports of Mario Mandzukic's transfer away from Bayern Munich gather pace in the German media.
Mandzukic was omitted from Bayern's squad for the 2-0 DFB Pokal final win over Dortmund on May 17. Despite scoring 18 goals in the season just ended and with a valid contract until 2016, the attacker is surplus to requirements under Pep Guardiola.
While Bundesliga top scorer Robert Lewandowski will be the new main man in Bayern's attack, Mandzukic has been linked with a switch to the Premier League, with Chelsea and Arsenal among the clubs named as potential buyers.
Mandzukic is currently preparing for the 2014 World Cup in Brazil, where Croatia will kick off the tournament when they face the hosts on June 12.
And the final details of any move may have to be completed quickly, with Kovac taking a firm line on the presence of agents at Croatia's training camp in Austria.
"With me there will be no player agents in the hotel lobby. They can do that over the phone. That's what I have made clear from the start," he was quoted as saying by German broadsheet Die Welt.
On Monday, the German football weekly kicker reported that Mandzukic could sign for a new club ahead of the World Cup. This would come as good news for Kovac, who said he hopes that his attacker will not carry the transfer discussion into the World Cup.
"I'd be delighted to have it off the table [before the first match]. But I can't influence it," Kovac said. "It's great to have such world class players in our small country. He can play everywhere in Europe. I am not worried about Mario."
