PORTO, April 17 (Xinhua) -- Liverpool reached the Champions League semifinal after comfortably beating Porto 4-1 on Wednesday, with the attacking trio of Sadio Mane, Mohamed Salah and Roberto Firmino grabbing a goal each.

Virgil van Dijk also scored for Liverpool, which advanced 6-1 on aggregate after winning the first leg 2-0 at home.

Liverpool took control after Mane scored a goal in the 26th minute that was confirmed by video review after being initially disallowed for offside.

Salah added to the lead in the 65th and Eder Militao scored for Porto in the 69th, but Firmino ended any doubts in the 77th and Van Dijk closed the scoring in the 84th at the Estadio do Dragao.

Liverpool, which lost in the final last season, will now face Barcelona, which eliminated Manchester United 4-0 on aggregate on Tuesday.

Porto, which eliminated Roma in the round of 16, had won all of its four home games in the Champions League this season, outscoring opponents 11-3.

It was the second consecutive elimination for the Portuguese champions against Liverpool. The English side routed Porto 5-0 at the Estadio do Dragao in the first leg of the round of 16 last season, with Salah, Firmino and Mane scoring all goals. Liverpool advanced after a scoreless draw at home, and eventually made it to the final where it lost to Real Madrid.
