James McArthur canceled out Emre Can’s opener after latching on to a huge Dejan Lovren error, only for the Croatian to make amends a few moments later with a header that put Liverpool ahead.

McArthur equalized again just after the half-hour mark, though, with Alberto Moreno in the firing line this time as he failed to close down Wilfried Zaha, whose cross teed up the former Wigan Athletic midfielder.

Further Liverpool goals from Joel Matip and Roberto Firmino ultimately sealed victory for Klopp’s men and the German is certain his team will shape up at the other end with time.

“We will sort the defense and then, what happens [regarding a title challenge], we will see,” he told reporters. “They can defend really well, it’s normal and I know for this game that everybody will talk about this.

“But inside a football team I don’t think it’s new. I don’t go into the dressing room and say ‘you are a really bad defender and you are the goalkeeper, where are you?’

“They are all human beings. We work on it and I am completely convinced about the quality. If they make mistakes and stay in the game then it’s a very good test for them and they stayed.

“I’m happy with the reaction. Not with the situation, not with the start of the game, that’s what we have to work on. I’m fine, we will work on it and see where it leads us to.”
