Jurgen Klopp's men head into the tie as 14/1 sixth favourites to win the Champions League, while their hosts up against odds of 100/1.
Strong points/weak points - what must Porto beware of and what can they exploit? There has been just one sorry group stage elimination from this competition since 2009, surrounded by a few mixed and all ultimately unsuccessful ventures through the Europa League.
However, facing the Egyptian star will probably be the biggest challenge for him this season. At times, the Reds were undone were by their leaky defence in the group stage. Karius started the City game and has played in Liverpool's four league games since.
Formation and playing style - what system do Liverpool usually play?
Having been ineligible to play a part in the club's Champions League success, he will be even more determined to guide his side to a third European Cup title.
The Cameroonian forward missed Porto's last league game against Chaves with a muscle problem, although the club have not given further details about the injury. Yacine Brahimi and Moussa Marega provide pace and trickery as well. Felipe is suspended for the game. At the back, the marauding runs of Alex Telles and Ricardo Pereira will be key. The most obvious suggestion is Jordan Henderson. We are in Porto and that is the only thing.
"Clyney is back; of course, it is absolutely too early to think about him, but he is back in normal training, so that's cool", enthused Klopp, clearly happy to have him back on the pitch.

Praise was rightly poured on Roberto Firmino and Mohamed Salah for their destruction of Southampton last Sunday. Their two previous encounters in Portugal both ended in draws. They haven't progressed past the quarter-finals since they lifted the trophy in 2004 under Jose Mourinho.
He netted five of the team's 15 goals in the group stage of the Champions League. "Hopefully we can keep another clean sheet and get an away goal". He has been involved in most number of away goals this season (4 goals, 2 assists).
A tough test awaits.
"I am feeling good and getting consistent game time helps a lot", the 24-year-old is quoted as saying by The Telegraph.
Two former Champions League winners lock horns on Wednesday in what should be an under-the-radar mouthwatering contest. They're doing it week in, week out and when one of them is struggling, the other one pops up, or the other two will pop up.
Meanwhile, Porto will be hoping that their Cameroon hitman Vincent Aboubakar is deemed fit to face Liverpool.
"We can make one mistake, that is how it is in life".
