Liverpool boss Jurgen Klopp expects a major challenge against Newcastle United on Sunday.
Klopp admits he's been impressed by Newcastle's market work.
He said, Incredibly strong team, in the Champions League and fully deserved with super development under Eddie Howe and smart business.
"Sandro Tonali and Harvey Barnes are really good business; they have a super intense style and massive atmosphere there so this is a tough one for sure.
"They played a really good first game where Aston Villa were good as well, the result didn't reflect the full game."
Klopp said of their defensive depth: "We have to be lucky with injuries I have no doubt of the quality of the boys we have.
"In this moment we are covered, but it is not dreamland where you can be prepared with every situation we have had to learn this is in the past.
"We have to try our best for next week, a squad where we can react on pretty much everything, 'Is it possible?'. We will see."
