Premier League leaders Liverpool host champions Manchester City on Sunday with both sides chasing history in a huge clash at the top of the table.
With the Carabao Cup already secured , Liverpool are seeking an unprecedented quadruple, while City could become the first team to win back-to-back Trebles.
It could also be a final league meeting between Jurgen Klopp and Pep Guardiola.
“I do the job myself so I see excellence when I face it and Pep is definitely that,” said Klopp.
Liverpool and City have won every Premier League title since 2018, with Klopp’s side finishing top in 2020 and Guardiola a five-time winner.
“The way he has influenced football, winning the amount of trophies he was won in his career,” added Klopp. “But if you see him on the touchline he behaves like he has never won before. The desire he has is absolutely outstanding.
“In my lifetime he is the outstanding manager, definitely.”
