Jurgen Klopp has delivered a warning to Paris Saint-Germain by insisting the French champions are yet to face a team like Liverpool.
Liverpool begin their Champions League campaign on Tuesday as PSG arrive at Anfield, boasting the world's two most expensive players, Neymar and Kylian Mbappe, as well as Edinson Cavani.
But Klopp has stressed that his side, containing the prolific frontline trio of Mohamed Salah, Sadio Mane and Roberto Firmino, will also represent a stern test for PSG in the Group C opener.
"I can't prepare a team to face Paris Saint-Germain without showing them the strengths of Paris," Klopp said.
"But, on the other side, it's quite difficult to make a preparation because they have never played against us. Us playing against them will look different to what they have faced so far this season -- that's the truth.
"I watched Paris. I watched them last year and I watched them this year, and it is impressive.
"They are good, really good, not only for Paris, but Kylian Mbappe, come on, what a World Cup he played. And Neymar, we all know about his quality. [Angel] Di Maria, maybe he didn't have the best time at Man United but all the rest of his career was outstanding. Cavani, a proper goal-getter.
"In the preparation, I have to make sure we know about it. I know we are quite good, and --respecting them without getting afraid of them -- but respecting them we have to.
"Do I have to compare them? I love my players, all of them, so I don't want to change anything. I wouldn't change them."
Firmino missed Liverpool training on Monday evening with the abrasion of the eye he suffered against Tottenham Hotspur on the weekend and will be a late fitness check for the PSG game.
Meanwhile, Klopp has paid tribute to the talents of World Cup winner, Mbappe, who he wanted for Liverpool back in the summer of 2017.
Sources told ESPN FC that Liverpool were continually monitoring the situation of the then-Monaco forward before he ended up moving to PSG that same summer.
"I love him, to be honest. What a player he is and a nice lad as well, so he's a really good kid," Klopp told RMC Sport. "What a player, what a player.
"Everyone knows him since he was 16, 17, when he impressed in Monaco's youth teams, and I saw videos of him when he was 17 and he destroyed defensive lines as he is doing now.
"He's at an unbelievable level of consistency at that age. He's an outstanding player, that's clear, but he can deliver, deliver and deliver, which shows he's really good educated boy and he knows what he is doing."
