Sam said that he expects more competition for his place than at Bayer Leverkusen, but that is a challenge he is looking forward to.
"I've settled in well and definitely want to achieve great things here," he told Bundesliga.com. "We want to finish in the top three and get at least as far in the Champions League as we did last season. If Bayern or Dortmund slip up, we want to take advantage.
"Competition for places is always good, every player benefits from it and that's the way it should be. It's the way you improve and I'm looking forward to it."
Sam played for Leverkusen for four years before joining Schalke.
