Gabriel Jesus (knee), Oleksandr Zinchenko (calf) and Takehiro Tomiyasu (niggle) remain doubtful after missing Saturday’s 5-0 win at Burnley.
Porto could be without Mehdi Taremi after the club confirmed the Iran striker was struggling with a thigh injury sustained in training on Sunday.
The Portuguese side are already missing Nigeria full-back Zaidu Sanusi, who is out for the season with a knee injury, with centre-back Ivan Marcano another long-term absentee.
