Manchester City manager Pep Guardiola has named the toughest coach he's come up against in his career, but snubbed Jose Mourinho.
The Spaniard has established himself as one of the word's best managers after enjoying great success at Barcelona, Bayern Munich and now in Manchester.
Many will remember his rivalry with Mourinho in LaLiga, but Guardiola reveals Jurgen Klopp's Liverpool has been his toughest opponent.
"The toughest opponent I've ever faced in my career is this Liverpool from last year and this one," Guardiola told DAZN.
"If you let yourself be dominated, they lock you in the area and you can't escape. When you dominate them, they run into space like no one else. They are very fast going backwards. They are very strong strategically. Their players have great mental strength. [Klopp] is the rival who has made me think about how to beat him the most.

"I have always said that Real Madrid are a very strong team in my career, they helped me to become a better coach with tough matches and competitions with Jose Mourinho, [Manuel] Pellegrini and all the coaches they had," he added.
"If you ask me which has been the most difficult rival for me to face, it has been Liverpool. The first years when I arrived in England, Liverpool were a bit weaker than now and Real Madrid were stronger. Now, this Liverpool are the hardest I have come across in my coaching career."
