Jose Mourinho is rarely one to praise his rivals, least of all Liverpool, so the fact that Jurgen Klopp brought some positivity out of the Portuguese is notable.
Mourinho had plenty of run-ins with the Reds during his two stints as Chelsea manager. He was linked with the job before Rafa Benitez's appointment, and the 2005 'ghost goal' incident was one of many run-ins between the two clubs in the first few years of the century.
Nearly a decade later, with Brendan Rodgers in the Liverpool dugout, Mourinho's Chelsea dealt the Anfield side a devastating blow in their title chase. In 2019, though, Rodgers' successor Jurgen Klopp won his counterpart around.
