Despite a massively impressive 4-0 win away at Porto, Klopp believes that anything can happen in the return leg.
"No, of course not, why should I [think we are through]?" he said.
"We came here to create the basis for the second leg at Anfield – and that's what we did, not more, not less.
"As I said a few times, I am too long in the business to think anything is sorted before the final whistle. We owe our supporters at Anfield a 100 per cent performance and that's what we want to deliver. That's all."
