If the Reds lose to Tottenham Hotspur, it will Klopp’s third defeat in the competition and his sixth loss of his seven finals as a manager.
“If Jurgen wins it’s an incredible achievement for him,” Mourinho told Sky Sports.
“If Jurgen doesn’t win, you know….to lose three Champions League finals…phew…that has to be really, really hard.
“But he is a very positive guy, I’m sure he’s just thinking about winning.
“Being a manager, and understanding what it means for a manager to play a Champions League final, there is always a negative side of it and the negative side is that one team will lose and one manager will lose.”
