BERLIN, Aug. 5 (Xinhua) -- Thomas Mueller's hat-trick smoothed Bayern's way for the second round meanwhile Schalke carved out a hard earned 2-0 win over fifth division side Noettingen to close the first round of the DFB Pokal on Monday.
Defending champions Bayern Munich cruised to a 5-0 triumph over fourth division team Rehden.
The Bavarians needed some time to warm up but with 15 minutes into the match when Xherdan Shaqiri broke the deadlock from three meters following an assist by Arjen Robben. Despite the early deficit Rehden were able to keep the German giants on distance. Nonetheless, Thomas Mueller headed home a cross by Rafinha following a corner to double the lead seconds before the break.
Bayern remained focused at the second half as Mueller donated another two goals to seal his hat-trick within five minutes. Yet, the treble winners were not done with the scoring as Arjen Robben rounded off the 5-0 win over courageous but hapless fourth division side Rehden.
Such matches are always dangerous. Therefore we are satisfied that we progressed, Bayern coach Josep Guardiola said.
Elsewhere, fifth division side Noettingen gave Champions League participants Schalke a hard time. The Royal Blues were fortunate that Mario Bilgers and Holger Fuchs attempts only rattled the bar at the opening period.
However, it were Schalke that opened the scoring with 30 minute on the clock as Klaas Jan Huntelaar slotted home clinically after a cross by Christian Fuchs.
Finally, New youngster arrival Leon Goretzka made it 2-0 on the scoreboards in the dying minutes of the match.
"We played arrogant from the beginning. We need to be happy that we progressed into the next round. That the only positive thing," Schalke coach Jens Keller said.
