Porto will have to play without star player Oliveira, who scored a stunning free-kick against Juventus to send the Portuguese side through to the quarter-finals.
Porto Predicted 11
Porto's star man Oliveira, who's scored 19 goals in all competitions this season, will miss the first leg due to an accumulation of yellow cards, so Marko Grujic could come back into the team to provide some defensive stability.
Mehdi Taremi is also suspended after his sending-off in Turin, so Luis Diaz could move into a central role, but Martinez will hope to get the nod after his crucial goal against Santa Clara.
Pepe returned to the starting lineup against Santa Clara and will marshal the defence once more, while Malang Sarr is able to feature against his parent club, but he is unlikely to be considered for a start.
Out: Sergio Oliveira (suspended), Mehdi Taremi (suspended), Mouhamed Mbaye (ACL)
Doubtful: Ivan Marcano (muscle)
Chelsea Predicted 11
Jorginho and Mateo Kovacic are set to pair up in the engine room once more, even with N'Golo Kante expected to be fit enough to make the journey for the first leg.
Christian Pulisic should also be involved despite entering the treatment room at half time during the defeat to West Brom, and it remains to be seen if Antonio Rudiger will play following reports of a bust-up with Kepa during a training session.
Silva's red card at the weekend means nothing for this game, but Andreas Christensen will hope to earn a recall to the side, especially if Rudiger is not selected to travel.
Doubtful: Christian Pulisic (hamstring), N'Golo Kante (hamstring)
Chelsea come into this game on the back of a 5-2 loss to Sam Allardyce's West Bromwich Albion on Saturday in the English Premier League.
A first-half brace from Brazilian midfielder Matheus Pereira, a second-half brace from attacker Callum Robinson and a goal from Senegalese striker Mbaye Diagne sealed the deal for West Bromwich Albion.

Chelsea were shocked by West Bromwich Albion on Saturday and will be keen to get back to winning ways.
Given their talent in the squad, Thomas Tuchel's men are regarded by many as the dark horses in this season's competition, and with Porto missing key squad members, Chelsea will be the favourites to win here.
