Poland striker Robert Lewandowski has said Borussia Dortmund must bounce back after their humbling defeat by Hamburg at the weekend when they play Zenit St Petersburg in Tuesday's Champions League last 16, first-leg clash.

Last season's Champions League finalists Dortmund suffered a shock 3-0 defeat at relegation-threatened Hamburg on Saturday, just three days before their European clash in Russia.

Lewandowski, who has scored 14 goals in 22 Bundesliga games this season, plus four in the Champions League, managed to play only an hour in Hamburg after suffering from a cold and has said Dortmund must perform better at the Petrovsky Stadium.

"We want to put in a good performance and get at least an away goal," said the 25-year-old.

In terms of personnel veteran defensive midfielder Sebastian Kehl is likely to replace Sven Bender, who is expected to miss the next ten weeks with an inflamed pelvis.

Dortmund flew to Russia on Monday and will be hoping Zenit are suitably rusty having last played a competitive match in December.

Dortmund CEO Hans-Joachim Watzke has said the Germans need a good result ahead of the return leg at Westfalenstadion on March 19.

"It will be very difficult, we are up against a strong team, but there is no real alternative to a good result."
