Leroy Sané scored twice as Bayern Munich set a UEFA Champions League record by extending its unbeaten run in group play to 31 matches with a 5-0 win over Czech champion Viktoria Plzen on Tuesday. Sané opened the scoring in the seventh minute when he coasted past several defenders before unleashing a shot inside the top left corner, and Leon Goretzka pushed the ball through for Serge Gnabry to make it 2-0 in the 13th. Sadio Mané and Eric Maxim Choupo-Moting scored the other two goals.
