The 20-year-old was at the heart of all the Reds’ best attacking moves and it was his parried shot which produced the early breakthrough goal from Mohamed Salah.
Jones continued to have a significant influence as Sadio Mane, Salah again and substitute Roberto Firmino all scored and Klopp’s side made it 14 goals in their last three visits to the Estadio do Dragao since 2018.
Porto coach Sergio Conceicao, whose only consolation was seeing Mehdi Taremi briefly make it 3-1, admitted his team’s performance was not up to the standard required.
“The five goals we conceded are the kind you concede when you are in a relaxed training session and not when you’re playing in the Champions League,” he said.
“Too many mistakes in danger areas. Everything was bad, but the responsibility is mine.”
