Liverpool eased into the Champions League semifinals with a comfortable 4-1 win at Porto.
Leading 2-0 from the first leg at Anfield, goals from Sadio Mane, Mohamed Salah, Roberto Firmino and Virgil van Dijk underscored an accomplished win by Jurgen Klopp's side.
Reds boss Jurgen Klopp said, "We played better this season. It was always going to be a whirlwind here and that was what it was. Second half the energy level dropped for Porto and we could control the game and score the goals.
"We are more experienced, that is clear. We had difficult away games and we knew it would be the same as at City and Roma last year. It is all good. A difficult game but we go to the semi-finals.
"It is first time for me to play Barcelona, apart from in friendlies. I am looking forward to that."
