The Turkish international joined the Reds on loan during the summer from Real Madrid.
They snapped him up after seeing the 24-year-old dominate the midfield from a holding role for Borussia Dortmund.
Sahin insisted: "I've played my whole career deeper but I have played as a No 10 here. It was new for me but I tried my best.
"If I could choose a position it would be holding as I feel more comfortable there."
