Jurgen Klopp 's star-studded Liverpool squad currently find themselves fighting on all four trophy fronts, but they aren't the only incredible side the German has ever assembled.
During his time with Borussia Dortmund, the current Reds boss transformed the Black and Yellows from mid-table also-rans into German juggernauts. Klopp won five honours during his glittering seven-year spell at the club but his finest achievement with Dortmund arguably came back in 2012.
Fresh from winning their first Bundesliga title in over a decade the previous year, Klopp's side enjoyed a record-breaking season which saw them retain their crown with a then-record number of points and league wins, in addition to claiming the DFB Pokal with a stunning 5-2 thumping of Bayern Munich. It's fair to say Klopp's double-winning side were quite the force.
