The Turkish midfielder has played his part in the Signal Iduna Park outfit’s recent resurgence domestically.
Although the influence of star players Marco Reus and Mats Hummels will be highlighted as a key reason for Borussia Dortmund’s recent improved form, an unsung hero that floundered in the Premier League has also played an important role.
The Turkish playmaker started fixtures against Freiburg, Mainz, Stuttgart and most-recently Schalke in the Ruhr derby, with Dortmund picking up a maximum 12 points from the clashes.
The former Feyenoord loanee has sparked an exciting central midfield partnership with Ilkay Gundogan, with his work-rate, range of passing and ability to win the ball back impressive.
Sahin spent half-a-season on loan at Liverpool from Real Madrid in 2012-13 but was unable to show the form that made him a real star in his first stint with Dortmund.
The 26-year-old only started six Premier League games and scored one goal before departing Anfield with something of a sour taste in the mouth.
With Sahin getting back to his best and Steven Gerrard set to leave Liverpool this summer, Brendan Rodgers will be scratching his head to why the Turk did not work out as many had hoped during his short-lived stint on Merseyside.
