Divock Origi was named in Liverpool's side to face Porto in the second leg of their Champions League quarter-final.
The 23-year-old Belgian, a substitute in the first leg which Liverpool won 2-0, got the nod up front ahead of Roberto Firmino who dropped to the bench as one of three changes made by Jurgen Klopp.
There were also starts for James Milner and Georginio Wijnaldum as Naby Keita and Jordan Henderson took their places amongst the substitutes.
