Liverpool could welcome back the long-term absentee as they look to complete the job against the Portuguese side in the Champions League
The 21-year-old returned to the bench for the 2-0 victory over Porto last week and, with Dejan Lovren unavailable through illness, is a contender to start at centre-back in the reverse encounter.

“He is getting better and better,” Klopp said at Tuesday’s pre-match news conference.
“Whether he’s ready to play 90 minutes from the start in a Champions League game, I’m not so sure.
“Can he come on and do a great job? I would say yes, that is possible, and that’s the most important thing for us.
Liverpool are in a strong position to advance to the semi-finals thanks to the goals scored by Naby Keita and Roberto Firmino at Anfield.

“It’s a compliment but we know we have a tough job to do. We are here to go to the next round. We have to fight really hard.”
