Lyon coach Paul Le Guen has warned against any complacency ahead of tonight’s second leg tie with Werder Bremen.

The French side look set fair for a place in the quarter-finals after winning the first leg 3-0 at the Weserstadion two weeks ago.

Furthermore, Lyon remain unbeaten at home in all competitions in 2004-05, while Bremen have not won in France in four attempts. But, Le Guen is taking nothing for granted.

“The important thing is that we don’t make history by becoming the first team to lose such a lead at home,” he said.

“If we don’t approach the game with humility and caution, we’ll be in trouble.”

“We haven’t forgotten the way they attacked us,” Le Guen continued.

“They’re a quality team and have achieved great things in the last year and a half.”

“The players will obviously have the first-leg score in their heads,” he said. “We need to defend well first and foremost, then attack when we can.”

Jérémy Clément may come in to strengthen the midfield, with forward Pierre-Alain Frau dropping to the bench and Wiltord playing a lone striking role.

Defenders Anthony Réveillère and Claudio Caçapa are still out, meaning Michael Essien will play alongside Cris at centre-half

Bremen coach Thomas Schaaf, meanwhile, acccepts that attack in Werder’s best policy tonight.

“We need to attack from the start because 90 minutes is not a long time to score four goals,” Schaaf explained.

“We’ve been very disappointed with recent results,” he said. “But if we get an early goal it might give us a lift and put some doubt in the Lyon players’ minds.”

Bremen have captain Frank Baumann back from suspension, though striker Ivan Klasnic, who has recently returned from a calf injury, looks set to be on the bench as Schaaf is expected to start with Miroslav Klose and Nelson Valdez up front.

Probable teams:
Lyon: Coupet; Diatta, Essien, Cris, Abidal; Juninho Pernambucano, M. Diarra, Clement; Govou, Malouda; Wiltord

Werder Bremen: Reinke; Stalteri, Ismaël, Pasanen, Schulz; Borowski, Micoud, F. Ernst; Klose, Klasnic, Valdez
