LIVERPOOL -- Jurgen Klopp has said his players will not underestimate struggling Sunderland at Anfield on Saturday.
Sunderland are 19th in the Premier League but have won their last two matches after failing to secure a single league victory before that.
And Klopp warned the home fans that they should not expect an easy afternoon, saying: "Sunderland is a real challenge.
"It's like the points are already [won] -- and we couldn't be further away from having the points already. We will not underestimate them, 100 percent not.
"If one person in the stadium would underestimate them, it would be the first mistake we could make.
"The weather will be good on Saturday and everything is prepared for a good football game if we do our job, which will be a difficult one."
He said he was pleased with his side's performances as they look to return to winning ways after a goalless draw at Southampton last time around.
But Klopp stressed the need to be wary and added: "It's the best moment Sunderland had in the season, and if you watch their games -- and we watched a lot in the last week -- you can see even when they lost at the beginning of the season, it was never a clear result.
"[They lost] 2-1, 1-0, 94th minute -- things like this. They were really unlucky in a lot of moments.
"We need to be ready for this game, that's the challenge."
