We take a look at Jurgen Klopp's most used players during his time as manager of Borussia Dortmund.
Roman Weidenfeller played 280 times under Jurgen Klopp for Borussia Dortmund, proving an integral part of a squad that won back-to-back Bundesliga honours, clinching the title in 2010/11 and 2011/12.
Neven Subotic played at the heart of Klopp's Dortmund defence, forming a formidable partnership with fellow central defender Mats Hummels.
Despite staying at the club three years longer than Klopp, Subotic's only two league titles came when the German was in charge.
To complete the core of the Dortmund defence is Mats Hummels, having played 247 times under Klopp.
Despite making the controversial, direct switch between domestic rivals Bayern Munich and Dortmund on numerous occasions, he is admired by both fan bases, currently representing Roma in Serie A.
Kevin Grosskreutz is considered one of the unsung heroes of Klopp's Dortmund squad that came so close to UEFA Champions League glory in the 2012/13 season.
Playing either as a right-back or right midfielder, Grosskreutz made 236 appearances under Klopp.
No one quite defines loyalty like Marcel Schmelzer, who spent the entirety of his football career playing in front of the Yellow Wall.
233 of his 367 Dortmund appearances came under Klopp.
Now a part owner of Polish football club Wisla Krakow, Jakub Blaszczykowski enjoyed a lengthy playing career, representing Dortmund for the best part of nine years.
Blaszczykowski was a constant in Klopp's starting XI at Dortmund, having played 226 times under the manager.
Lukasz Piszczek proved himself as one of the Bundesliga's most consistent full-backs during his time at Dortmund, using his versatility to become an invaluable part of Klopp's squad.
Robert Lewandowski is arguably one of the greatest centre forwards of this generation, so to see that he played 187 times under Klopp at Dortmund is no surprise.
He scored 103 times in 187 games under Klopp's management, before moving on to Bayern Munich in 2014.
Sven Bender broke through into the Dortmund senior setup with Klopp in charge, making his Bundesliga debut on 19th September 2009 in a game against Hannover 96.
Nuri Sahin enjoyed two separate stints at Dortmund, playing under Klopp on both occasions.
Leaving the club to sign for Real Madrid in 2011, he would return on a loan deal between 2013 and 2014.
