Although Royal Blues' coach Jens Keller has singled out Chelsea as "one of the favourites for the title", he believes there is no reason for his side to feel inferior.
"Just a glance at Group E as well as our recent results in the Bundesliga give us self-confidence, of course," Keller said at a press conference in Gelsenkirchen.
"We're at home and Chelsea are going to feel that from the very first minute."
Keller is set to welcome Kevin-Prince Boateng back into his side after he missed the 3-2 win at Eintracht Braunschweig on Saturday with a knee injury.
"Things are looking good with him," said Keller, who should also be able to restore regular number one Timo Hildebrand in goal and Jermaine Jones in midfield for Marco Hoger, who has been ruled out for six months due to a serious knee injury.
Hoger joins Klaas-Jan Huntelaar as a long-term member of the treatment room, but Keller prefers not to waste time worrying about the players he is unable to select, Jefferson Farfan and Kyriakos Papadopoulos included.
"We shan't talk about misfortune and feel sorry for ourselves," he said. "We've got to take the situation as it is.
"Every player who goes out there will give it their best."
No more so than Julian Draxler, who is seen as a potential Barclays Premier League player from next season.
The Germany international penned a new deal until 2018 last summer with Schalke turning down lucrative offers from unnamed English clubs, but the midfielder insists he is not thinking about playing himself into the shop window at the Veltins-Arena.
"Many of Europe's top clubs come from England so of course there's an attraction to play there, but I've just extended my contract and we're in the middle of the season so I'm not wasting any thoughts on that," said the 20-year-old.
