Bayern Munich strolled into the third round of the DFB-Pokal with a 4-0 victory over Kaiserslautern at the Allianz Arena on Wednesday.
Claudio Pizarro opened the scoring with a cool drive from the edge of the box, and Arjen Robben's first goal of the season put the hosts into a commanding advantage just after the break. The Peruvian forward made it three soon after, and his Dutch colleague added insult to injury with a late fourth.
Bayern had suffered a disappointing 2-1 loss to Leverkusen at the weekend, but looked eager to get ahead early to avoid any upset, with the returning Robben darting in off the right and firing a shot just over the bar.
Robben then received a Rafinha long ball on the right wing, tickled the ball between two defenders, and Pizarro was there to drive the ball past Tobias Sippel and put his side a goal ahead.
Falling behind failed to dampen Kaiserslautern's spirits, though. Idrissou had another chance to net soon after, but Tom Starke, making his Bayern debut, palmed his shot wide, before Steven Zellner struck the woodwork with an ambitious effort from distance.
Eventually, the match settled into more of a rhythm, with Bayern controlling possession in the center of the park, but the hosts had a brilliant opportunity to extend the lead when Diego Contento's cross cannoned off Robben to Alaba, whose first-time volley was superbly parried by the Lautern keeper.
Bayern started a seige of the visitors' goal shortly after the break, and Sippel was forced into another save within seconds when Shaqiri tried an acrobatic volley from the edge of the box.
Seconds later, however, the hosts finally doubled their advantage. An awful Leon Jessen header fell straight to Pizarro, who nodded it onto Robben, and the Dutchman smashed it home from close range.
It was not long before the third arrived. Shaqiri swung in a free-kick from the left wing, and Pizarro, completely unmarked, headed home from the edge of the six-yard box.
Alaba then fired an ambitious effort high and wide from distance, before Pizarro missed an excellent opportunity to complete his hat trick, taking a heavy first touch in the area and allowing Sippel to claim the ball.
It looked as though three would be enough for the visitors, but seconds before full-time, Robben made it four. Pizarro was sent clean through, only for Marc Torrejon to tackle the former Werder Bremen forward and gift the ball to the Dutchman to round off an easy night for the Bavarians.
