City have won the Premier League title for three of the past four seasons, with Liverpool's first top-flight title for 30 years in 2019/20 halting a clean sweep. Chelsea and Manchester United have been talked up as title contenders this season after spending big in the transfer market. But Klopp believes City remain the team to beat as they showed in a 1-0 win at Chelsea last weekend which was more convincing than the scoreline suggests.
"They are still really, for me, probably the best team in Europe in the moment and it's a tough one," said Klopp on Friday. "Last weekend, they played Chelsea and everybody was talking about Chelsea, how good they are - and they are good, oh my God, they are really good side but City was clear, clear better that day."
City boss Pep Guardiola said on Friday his personal duels with Klopp have made him a better manager. In 21 meetings between the pair, both have won nine with three draws. Liverpool go into the weekend a point clear of City, Chelsea and United at the top of the table. But Klopp knows his side will have to be at their best to stay there come Sunday night.
"This is a really special game of the season, every year it is always the same. It has to be high intense because if it's not high intense, I would say then City is really difficult to play against," he added. "You have to be brave, you have to be front-footed, you have to be cheeky in moments, you have to be really your best version and then, but only then, you have a chance."
Trent Alexander-Arnold and Thiago Alcantara will both be missing for the Reds due to injury, but Klopp is hopeful both will be fit to return after the international break.
