“The person who has the problem is the guy responsible for leaking that information, because at the end of the day, he might be damaging the hopes of a nation. “Maybe that person hasn’t understood how team team sports work. I think it is a shame, but we won’t be hiring any detectives.” Low has already addressed the squad about the issue and has said: “It is not good when the cards are on the table so early”. Now Lahm insists the Germans have to be more careful about who they pass team information too. “This is an issue for us, everyone has to be aware about who he gives information about team selection to,” said the 28 year-old. “We have to be extra careful from now on. “It is normal for players to tell their wives or girlfriends if they are playing or not, but it is out of the question to pass the complete line-up onto an agent. “We can share information with the closest family, but that is about it.” It was common knowledge ahead of the opening Group B match against Portugal that Low intended to play Gomez, rather than Miroslav Klose, up front and he dropped Arsenal defender Per Mertesacker for Borussia Dortmund’s Mats Hummels. News also leaked prior to the final group game against Denmark that Bayer Leverkusen midfielder Lars Bender would be used at right-back for the suspended Jerome Boateng.
