Liverpool boss Jurgen Klopp refuses to accept history is with them going to Champions League opponents Porto defending a 2-0 aggregate lead.

The last time they let a two-goal lead slip to lose a match was at Bournemouth in December 2016. That, however, has not stopped Klopp reinforcing the message that nothing has been decided.

"I always tell the boys the truth when I analyse," said Klopp. "I don't make things bigger or smaller than they are.

"When we play Manchester City, I don't say they have no clue about football or say it's the best team in the world. We analyse for us.

"There's no risk that I need to convince the boys that Porto are really good. They know it already. We played Roma and they can be an uncomfortable opponent but I didn't really see a chance for them when they played Porto (in the last 16). Porto were in control. So we should be prepared."
