The BVB goalkeeper believes his side should have been comfortable before a 1-1 derby draw at Schalke ended with a questionable handball claim
Borussia Dortmund goalkeeper Roman Burki conceded Marc Bartra could have been punished for handball in the penalty area as the 150th Revierderby with Schalke ended 1-1.
Pierre-Emerick Aubameyang's 24th goal in as many Bundesliga appearances this season gave Dortmund an early second-half lead but Thomas Tuchel's team could not make their superiority weigh any more heavily.
Left-back Thilo Kehrer struck 13 minutes from time, netting a first goal of his senior career with aplomb, and Dortmund were the side under pressure from that point as the noise levels ramped up at Veltins Arena.
