Borussia Dortmund continued their preparations for the new season as they breezed to a 4-1 victory over Luzern at the Swissporarena, Goal.com said . BVB, who will look to reclaim the Bundesliga title from rivals Bayern Munich in 2013-14, included new signing Henrikh Mkhitaryan and forward Robert Lewandowski among their starters on Tuesday, July 16.

And they made the perfect start to the match when forward Marvin Ducksch capitalised on a series of Luzern defensive errors to fire the away side ahead from Jonas Hoffman's delivery after nine minutes.

Lewandowski doubled the visitors' advantage soon after when he headed home a well-rehearsed set piece from Jannik Bandowski.

Luzern threatened an unlikely comeback in the 38th minute when Dario Lezcano scored, but Mkhitaryan struck just before half-time to restore Dortmund's two-goal cushion.

And there was to be no let up in the second period as substitute Marco Reus converted a Nuri Sahin delivery just ten minutes after the re-start.

The away side continued to press forward with Reus and new-boy Pierre-Emerick Aubameyang both going close, but they were unable to find another goal.

It was another good work out for Dortmund, who had secured 3-1 and 4-1 victories over Basel and Bursaspor respectively in their previous pre-season fixtures.
