Dortmund's Lukasz Piszczek retires from Poland duty
Poland defender Lukasz Piszczek says he is retiring from the national team following a poor World Cup performance.
Piszczek wrote on Instagram on Saturday that he was taking a "hard but rational" decision and was ending his "adventure with the representation."
In an interview for Wirtualna Polska, the 33-year-old Borussia Dortmund defender said his performance was a "great surprise" to him and that his physical condition failed him at the tournament in Russia.
Poland were eliminated in the group stage.
