Schalke 04 coach Jens Keller has admitted that he is "looking forward" to facing Steaua Bucuresti for the first time in his career in Wednesday night's Champions League Group E clash at Veltins-Arena.

Keller said that he does not consider Steaua as the weakest team in the group and thinks that his side must be at their best to win.

"I'm looking forward to the challenge," Keller told Bundesliga.com. "I've not come up against them before. Steaua are a hard-running outfit that go about their work really aggressively.

They're not really the outsiders in this group. They played really well in the Europa League last season. We're ready for them."

The other two teams in Group E are Chelsea and Basel.
