Jerome Boateng has hit out at the Germany fans who booed international teammate Mesut Ozil during Sunday's friendly against Cameroon.
The Arsenal midfielder was met by jeers from a section of supporters following a subdued display in the 2-2 draw at Borussia-Park.
"I do not understand, I cannot understand," Boateng told reporters.
"In that case people should not come to the stadium. That they whistle so early into the game. I do not understand."
Germany coach Joachim Low has admitted that Ozil is not playing his best football ahead of the World Cup in Brazil.
