The German champions are the leading scorers in the Bundesliga, with 49 goals in 22 matches, and they averaged two goals a game in the opening phase of the Champions League in qualifying behind Inter Milan.
They could not manage a clean sheet in any of their group stage home games however, and a doubt remains about their ability to play the cannier game required in the knockout rounds, where away goals count double in the event of an aggregate draw.
“We can’t afford to give our fans anything to cry about,” said Swiss defender Ludovic Magnin, who scored the opening goal in Werder’s 4-1 win over Hanover 96 on Saturday:
Lyon look well able to capitalise should Werder revert to their frantic attacking instincts, especially with Sylvain Wiltord returning to lead a three-man attack.
The French champions reached the Champions League quarter-finals for the first time last season and they are determined to turn it into a habit.
“The only thing we have in mind is to go as far as possible in the competition. Nothing else matters,” said captain Sidney Govou. But the French international striker made it clear they were not taking Werder lightly.
Lyon, who hold a six-point lead at the top of Ligue 1, had a real work-out ahead of the tie with a tense and physical 1-1 draw at Monaco, the other French team left in the Champions League.
Werder have captain Frank Baumann suspended but should otherwise be at full strength.
Miroslav Klose, Frank Fahrenhorst and Gustavo Nery all missed Saturday’s 4-1 over because of flu but are back in training. Of that trio, only German international striker Klose is likely to be picked in the starting line-up.
Lyon’s Bryan Bergougnoux, Anthony Reveillere and Cacapa are all out through injuries.
