The Club World Cup final on Saturday will be the first time Liverpool boss Jurgen Klopp has faced a Brazilian side during his time as Reds manager.
"I know what we have to expect," Klopp added.
"Flamengo will be intense, organised, [coach] Jorge Jesus has changed their fortunes and most of their things.
"They have different ways of playing and they have real quality in the centre of the park, they are cheeky on the wings and they can shoot from distance - just like a successful team should be.
"This is the first time that I have faced a Brazilian team but this is also the first time Flamengo have played a team like Liverpool."
