Sunderland, who lifted themselves off the foot of the table last weekend with a second successive win, are the visitors to Anfield on Saturday as former Everton and Manchester United manager David Moyes returns to his bogey ground where he has drawn seven and lost six of his last 13 visits.
Despite the Black Cats' struggles this season, Klopp is under no illusions about the difficulty of the task ahead despite his side scoring 19 times in six games at Anfield this season.
"It's like the points are already on the counter and we couldn't be further away from having the points already," he said.
"We will not underestimate them, 100 per cent not. If one person in the stadium underestimates them it would be the first mistake we could make.
"They (Sunderland) have not the highest amount of possession so that shows they are a counter-attacking team.
"But they don't only make counter-attacks, they have other strengths too with set-pieces.
"The funny thing is that after the draw (last weekend) it started again with the 'parking the bus' team thing but Southampton are not a 'parking the bus team'.
"It was a team which we forced to defend deeper and that can happen against any team.
"So I am excited about having the chance again to show we are still there and still in good shape and use this opportunity to fight for the result."
