The Dutch midfielder is set to make his European debut for his new team on Wednesday when Schalke visits Istanbul, and the former Inter star believes his side can triumph.
The Dutch midfielder is delighted to be playing in the top continental competition once again, having helped Inter win it in 2010, and is looking forward to the clash with Jens Keller's side.
"The Champions League is the top tournament of Europe,” he told Galatasaray TV. “We’re ready for the match and can’t wait to play it. It’s going to be a magnificent match. We should play our game and go to Germany with an advantage. In my opinion, playing home is the same, being in a better position than our opponents is what's important.
"We know our opponents’ strengths and weaknesses against us, but what really matters is how well we play. As a team, we are ready for a top game and we are going to mind our own business and go all out for a victory."
Galatasaray qualified for the knockout stage of the competition by finishing second in Group H behind Manchester United.
