Red card: Orban (13')
Javi Martinez had a couple of half-chances for Bayern in a lively opening, but the game's turning point arrived in the 13th minute, as Leipzig captain Willi Orban was sent off after barging into Arjen Robben on the edge of the area. Ralph Hasenhüttl sacrificed Timo Werner - the man whose missed penalty handed Bayern victory in the DFB Cup in midweek - for Ibrahima Konate, but that didn't prevent James giving Bayern the lead shortly afterwards with his first goal at the Allianz Arena. Lewandowski added a second from Martinez's killer through ball, although the Polish marksman was forced off with a suspected hamstring injury before half-time.
Leipzig made a bright start to the second period, pressing Bayern a little further up the pitch, but with 10 men their legs soon began to tire. The hosts were content to defend their two-goal advantage and had relatively few chances to add a third. David Alaba fired a free-kick just wide on the hour while James had a couple of efforts from distance, but the game had been put to bed long before the final whistle. Leipzig even went down to nine men late on, Naby Keita limping off with an ankle injury after Hasenhüttl had used all of his substitutes. While it has been a week to forget for the Saxony club, Bayern continue to go from strength to strength under Jupp Heynckes.
