The German club head to Old Trafford to meet Manchester United on Tuesday night and the Australian winger feels he and his teammates have enough quality to make life very difficult for David Moyes' men.
"We are in a difficult group, it's important to start well and this is a tough test. Everyone knows how strong Manchester United are, but we have the talent," he said.
"If we stick to the game plan, hopefully we can get a good result.
"The boys are up for it. We have a great opportunity to show how good Bayer Leverkusen are and hopefully I can be a part of that.
"United are an excellent side on paper, it may be a time of adjustment for them with a new manager, but they still have world-class players with plenty of strength up front."
As for his first visit to the Theatre of Dreams, the former Melbourne Victory and Fortuna Dusseldorf attacker added: "It'll be wonderful just to be in the stadium and to be on the bench and it'll be excellent if I get the chance to come on."
