Sweden's preparations for their World Cup clash against Germany have been hampered by a stomach bug that has prevented three players from travelling to Sochi, where Saturday's game will be played. Coach Janne Andersson revealed that defenders Pontus Jansson and Filip Helander, along with midfielder Marcus Rohden, were left behind at the team's tournament base further up Russia's Black Sea coast in Gelendzhik to avoid any danger of the illness spreading. However, the hope is that they will recover to come to Sochi in time for the match. "We have split the squad. We didn't bring them on the flight because we didn't know what had made them feel a bit queasy, but they will travel tomorrow," Andersson said at a press conference at Sochi's Fisht Stadium on Friday. Sweden's team doctor said in a statement on the official Swedish FA website that the trio were "on the mend".
