Diego Simeone and Jürgen Klopp have never faced off in a competitive game prior to Tuesday night’s Champions League round of 16 first leg tie between Atlético Madrid and Liverpool.

The two managers lead their sides out at the Wanda Metropolitano and Klopp is expecting a tough encounter against a “world-class results machine.”

The German coach spoke about Simeone in his pre-match press conference ahead of the mouth-watering clash. “People say I’m emotional on the sideline, but if I’m level four then Diego is on level 12. I’m the kindergarten cop compared to him.” “After [eight years as Atlético manager] to still have this emotional level, wow, it’s absolutely impressive. His teams are always world-class in terms of organisation, so that makes him one of the best. We met once or twice, we exchanged some messages after big wins or big defeats.”
