Porto v Liverpool
Liverpool go to Porto in the last eight of the Champions League with the tie very much in their favour after a 2-0 first-leg win.
The Reds secured a comfortable victory at Anfield last week when a deflected Naby Keita goal and a close-range tap-in from Roberto Firmino did the damage against the Portuguese giants.
Jurgen Klopp's side, who beat the same opponents 5-0 on aggregate in the round of 16 last year - scoring all the goals away from home - will be expected to safely get the job done on Wednesday and book their place in the semi-finals for the second year running.
Klopp could make some changes after Sunday's 2-0 Premier League win over Chelsea as he bids to keep his side fresh as they chase glory on two fronts this season.
In-form Mohamed Salah is set to start but there could be chances for the likes of Divock Origi, Daniel Sturridge and Adam Lallana, if he overcomes a minor knock.
Xherdan Shaqiri, meanwhile, will be eager to start his first game since January 30, while James Milner has had to play a peripheral role of late and he should start, with Jordan Henderson, who has a slight ankle injury, probably rested.
Dejan Lovren, who started the first leg, would have been in line for a recall after he sat out the Chelsea game but the Croatia international did not train on Tuesday due to an unspecified injury and may be absent.
Porto remain in good form themselves as, aside from the first-leg defeat, they have won six of their last seven games in all competitions and currently sit second in their domestic table, behind only leaders Benfica on goal difference.
Boss Sergio Conceicao has key midfielder Hector Herrera and experienced centre-back Pepe available after the duo missed last week's defeat through suspension while Moussa Marega, who did waste a couple of good chances in the first leg, is set to start up front alongside Tiquinho.
