Liverpool and Manchester City are doing battle for the Premier League title and both sides also remain in the hunt for the Champions League.
The Reds face Porto on Wednesday, holding a 2-0 advantage from the first leg, and Jurgen Klopp will be hoping for a repeat of their rampant 5-0 victory at Estadio do Dragao in last season s round of 16 a game in which Sadio Mane starred.
City, meanwhile, host Tottenham, with Pep Guardiola s side having to comeback from a 1-0 deficit, though Mauricio Pochettino will have to do without Harry Kane, who was injured in the first leg.
Here are some essential Opta Facts as we close in on the business end of the competition.
Porto v Liverpool
3 Mane scored a hat-trick for Liverpool versus Porto last term. Only Luiz Adriano versus BATE and Cristiano Ronaldo against Atletico Madrid have recorded more than one hat-trick against an opponent in the Champions League, while no player has got two away to one club.
7 Liverpool have never lost a European match against Porto in seven previous encounters, winning four times and drawing on three occasions, keeping three successive clean sheets in the process.
9 The Reds have progressed from all nine of their previous two-legged European ties under Jurgen Klopp (four in the 2015-16 Europa League, one 2017-18 Champions League play-off and four knockout stage fixtures in the same competition).
2 Two of the three teams that lost their first leg by two or more goals in the last 16 of this season s competition managed to turn the tie around in the return fixture; Manchester United v Paris Saint-Germain and Juventus v Atletico.
100 Porto are the only remaining side in the Champions League to have won all of their home games in the competition this season.
5 Liverpool s 5-0 win in last season s meeting at Estadio do Dragao was Porto s heaviest defeat in European competition.
