Robert Lewandowski said Borussia Dortmund must build on its home win over Marseille at Arsenal in its next Champions League match if it wants to repeat last season's run to the final.

Having lost 2-1 at Napoli two weeks ago in its opening Group F match, Tuesday's 3-0 win over Marseille leaves Dortmund second in the standings ahead of its away match at leader Arsenal on Oct 22.

Having thrashed Freiburg 5-0 at home on Saturday, Dortmund picked up where it left off in the Bundesliga with Poland striker Lewandowski scoring a double and Germany winger Marco Reus grabbing the other.
