Germany coach Joachim Loew is said to be fuming after a "mole" in the German camp again leaked their starting line-up at Euro 2012.
Loew sprung a surprise for Friday's quarter-final by dropping Mario Gomez, Lukas Podolski and Thomas Mueller for the Germans' 4-2 quarter-final win over Greece at Arena Gdasnk, but the news was reported earlier that afternoon.
"I can't say exactly from where this (leak) has come," admitted Loew ahead of his team's semi-final against England or Italy in Warsaw on Thursday.
"The players talk to their agents, perhaps it comes from there.
"They phone home and talk with friends, either because they are happy or disappointed.
"I am certain it doesn't come from the players. These are other channels, but they are unidentifiable.
