Borussia Dortmund will be looking for another three points in Champions League Group F on Wednesday, when they entertain English Premier League leaders Arsenal at the Westfalenstadion (Signal Iduna Park).
Two weeks ago in London, goals from Henrikh Mkhitaryan and Robert Lewandowski guided Juergen Klopp's men to a 2-1 win over 'The Gunners' - that result left three sides tied for the lead in the group on six points from three games after Napoli beat bottom club Marseille.
Dortmund have won eight out of eight home matches this season, including the German Super Cup, and warmed up for the visit of Arsenal with a 6-1 victory over VfB Stuttgart where Lewandowski scored a hat-trick.
Given that kind of form, especially at home, the Dormund support will be confident of achieving another success.
However, Arsene Wenger's team are not without a little confidence themselves, having beaten Liverpool 2-0 at the weekend, a result which helped Arsenal move five points clear at the top of the table.
Dortmund have never lost against English opposition at the Westfalenstadion, but Arsenal were within two minutes of winning there in September 2011 before the hosts scored a late equaliser.
Arsenal are also unbeaten in four away ties in Germany - the latest being a 2-0 victory over eventual European champions Bayern Munich in March.
