It is fair to suggest that if he has a nemesis at all, then for Jurgen Klopp, it is Real Madrid.
And yet for all the truth in that, he also had perhaps his finest moment as a manager against them, in one of the greatest performances a team has ever produced in the Champions League.
In a contest that crystallised the ragged campaigns of the two teams, with Madrid showing their vulnerability again, we saw echoes of that Klopp masterclass against Real, back in 2013, when his Dortmund team destroyed them 4-1 thanks to a tactical triumph.
