Bayern Munich secured a domestic double after beating RB Leipzig 3-0 in the DFB Pokal final at the Olympiastadion in Berlin on Saturday. Robert Lewandowski put the Bundesliga champions in front just before the half-hour mark with a difficult header from a David Alaba cross to give Bayern the lead at half-time. Manuel Neuer kept Bayern in front with his second big stop of the match, denying Emil Forsberg with a kick save after the RB Leipzig winger had broken free on goal. Bayern doubled their lead in the 78th minute when Kingsley Coman took a neat first touch on a loose ball in the Leipzig penalty area to set up a left-footed shot that he blasted past Peter Gulacsi. Lewandowski sealed Bayern's 19th German Cup soon after, outrunning his defender to a through ball and chipping Gulacsi to make it 3-0 with his 40th goal in all competitions this season. Bayern boss Niko Kovac brought on departing club legends Franck Ribery and Arjen Robben for a final runout in front of the Bayern faithful and the two almost combined for a fourth goal in the final match of their illustrious careers in Munich. The win sees Kovac, who won the double with Bayern as a player too, become the first head coach since Felix Magath in 2005 and 2006 to win back-to-back German Cups after his Frankfurt team beat Bayern in last year's final.
