Jesse Marsch made a succesful start in his maiden competitive game as head coach of RB Leipzig with a 4-0 away romp at second division Sandhausen on Saturday in the first round of the German Cup.

The American has replaced new Bayern Munich coach Julian Nagelsmann at Leipzig, who finished runners up in the Bundesliga and German Cup last season.

A week before the new German league season kicks off, Leipzig eased into the next round of the cup.

After new signing Mohamed Simakan had a first-half header disallowed in Sandhausen, his centre-back partner Willi Orban smashed in an Angelino corner to put Leipzig ahead.

Leipzig's former Eintracht Frankfurt striker Andre Silva hit the post before Mali midfielder Amadou Haidara fired in their second goal just before the break.

Having set up Haidara, French forward Christopher Nkunku combined with Silva for their third.

With Leipzig in control, travelling fans sang "still time for one more".

Substitute Dominik Szoboszlai, who joined for €20 million last January from sister club Red Bull Salzburg, obliged by scoring on his Leipzig debut after six months out with injury.

There were few problems elsewhere for top-flight clubs.
