Liverpool manager Jurgen Klopp says his team will “suffer” against Barcelona, but will also have chances in the first leg of the Champions League semi-final.
The Reds meet the Spanish champions at the Nou Camp on Wednesday (20:00 BST).
“Will we be perfect? That’s not possible. Will we make mistakes? Oh, yes. Will we suffer? Oh, yes, 100%,” said the German.
“Will there be moments when we have a chance? Yes, 100%. I hope we will use them – that is what we will try to do.”
Klopp, who guided Liverpool to last season’s final, added: “We can feel completely free to play our game. It is a brilliant team here at Barcelona.
“We were in contention last year, but they have been in contention for nearly 20 years. It will be so difficult, but I couldn’t be more excited to have the opportunity.
“I hope my players feel the same.”
