Sadio Mane continued his fast start to life at Bayern Munich as he scored his fifth goal in just sixth appearance on Wednesday night.
Bayern advanced to the second round of the DGB-Pokal after thrashing third tier side Viktoria Koln 5-0 away from home.
Sadio Mane scored Bayern’s third with a simple tap in after being teed up by Leroy Sane from the right side.
It marked his fifth goal for Bayern since making the £28.8million move from Liverpool earlier this summer.
His previous strikes came against RB Leipzig, VfL Bochum and Frankfurt in the Super Cup and Bundesliga, respectively.
Coach Julian Nagelsmann made seven changes to the team that drew against Borussia Moenchengladbach at the weekend with an eye on their Champions League game at Inter Milan next week.
His team needed time to settle in and new signing Ryan Gravenberch slotted in for a deserved lead in the 35th minute despite a gutsy performance by the hosts.
French teenager Mathys Tel, who also arrived this season, confirmed his status as one of the most exciting prospects in European football when he rifled in a fine solo effort on the stroke of halftime.
Tel should have scored again when he was sent through with only the Viktoria keeper to beat but Ben Voll stood his ground to deny the 17-year-old.
Substitute Jamal Musiala did better four minutes later, slotting in from close range before fellow substitute Leon Goretzka, on his comeback from injury, completed the rout.
Bayern will return to Bundesliga action on Saturday when they take on Union Berlin before turning their attention to the Champions League next week. (DailyMail)
