Sahin, who needs match sharpness, is one of the few players in a squad with the average age of 21 who has Champions League football experience.
"I love football and I am happy I can be a part of the game," he said. "We have a few players who can lead the team but I am one of the players with the most experience.
"I try to lead the team because I play central midfield and I have to take the responsibility and I am glad to do this.
"I want to play every game. Last year I played only a few games and this year I want to play every minute.
"Of course I need games to get to the level I long to be and this is a good chance for me."
