Germany will play three more friendly matches as part of their FIFA World Cup™ preparations, including a 15 May clash against Poland in Hamburg, the German football federation (DFB) said.
After that match, Joachim Low's team will host opponents, who are yet to be decided, in Monchengladbach on 1 June and in Mainz, four days later, with the DFB hoping to line up an African and another European team.
Germany had already lined up a home game with fellow qualifiers Chile in Stuttgart on 5 March.
The Germany squad will leave for Brazil on 7 June and be based at Santo Andre in the state of Bahia.
At the World Cup, Germany will be in Group G along with Portugal, Ghana and the United States.
