Bayer Leverkusen coach Roger Schmidt insists the Germans will not be settling for a draw when they meet Roma in a Champions League clash the hosts must win to have any realistic chance of qualifying for the last 16.

Two weeks after scoring two late goals to earn a 4-4 draw at the BayArena and deprive Roma of their first win in Group E, Leverkusen have Roma's backs to the wall.

A Leverkusen win at the Stadio Olimpico on Wednesday would force Rudi Garcia's men to win their last two group games, one of which is away to defending champions Barcelona, to have any chance of sneaking into the knockout phase.

It would also give Schmidt's men a huge qualifying boost, but even a draw would likely keep their destiny in their own hands, but Schmidt's not interested in that.

"We've lost away to Lazio and Barcelona already this season, and we certainly need to pay more attention, but that doesn't mean we've come to Rome to defend," Schmidt said.

Ahead of Wednesday's fixture, Roma's steady goals haul -- as well as Edin Dzeko's lean spell -- is under scrutiny.

Roma's 1-0 defeat to Inter Milan last weekend was the first time they had failed to score in 25 fixtures in all competitions, but Dzeko has netted only once in 11 outings for the Giallorossi.

Leverkusen are still smarting from a 2-1 defeat at Wolfsburg on Saturday when Nicklas Bendtner hit a clearly offside opening goal for the hosts.

On the plus side, ex-Manchester United and Real Madrid striker Javier Hernandez has hit great form of late, scoring six goals in his last four games, including a brace in the 4-4 draw a fortnight ago.

Schmidt added: "Javier Hernandez is playing better and better. He has scored a lot of goals lately."

Leverkusen's sporting director Rudi Voller, who scored 45 goals in 142 Serie A appearances for Roma in 1987-1992, said he "can't wait" to return to the 'Eternal City'.

"If we don't lose at the Olimpico it will give us a boost in terms of qualifying for the last 16, but it will be a difficult game," he said in an interview with www.gazzetta.it.

Leverkusen are missing ex-Germany defender Roberto Hilbert (knee injury) and still have doubts over Lars Bender (ankle) while Roma are without Malian midfielder Seydou Keita.
