Croatian centre-back Lovren returns at the expense of Joel Matip, while James Milner deputises for the suspended Andy Robertson at left-back.

Liverpool captain Jordan Henderson is also rewarded with a recall to the starting XI after coming off the bench to score in a 3-1 win at Southampton on Friday, with Georginio Wijnaldum dropping out.

Porto are also without two of their most experienced players through suspension as three-time Champions League winner Pepe and Mexican international midfielder Hector Herrera miss out.

Maxi Pereira and Danilo come into the side that beat Roma 3-1 after extra time in the last 16 to progress to the quarter-finals 4-3 on aggregate.
