Real Madrid and Liverpool will seek to continue their winning runs in the Champions League on Wednesday as both teams aim to preserve their perfect records in the competition.
Record 15-time champions Real Madrid travel to face AEK Athens, while six-time European winners Liverpool visit Fenerbahce.
Madrid coach Jose Mourinho, who has previously won the Champions League with Porto and Inter Milan, is hoping to claim another European title but said he was focused on securing qualification first.
"It would be the third with three different clubs, and this one with the biggest club in the world. But we are talking about hypothetical situations and I prefer real ones," Mourinho said.
He added that his team still needed points to advance and that he did not want to discuss the round of 16 before securing qualification.
Last season's runners-up Arsenal travel to Slavia Prague, while Manchester City face RB Leipzig away from home.
Mbappe maintains impressive scoring form
Real Madrid forward Kylian Mbappe enters Wednesday's fixture in excellent form, having netted 15 goals in 14 appearances this season, including seven in his last five matches.
The France international has also scored in each of his previous five Champions League appearances.
Meanwhile, teammate Jude Bellingham is close to setting another competition record. At 23 years and 128 days, he could become the youngest player to reach 60 Champions League appearances, surpassing former Madrid goalkeeper Iker Casillas, who achieved the milestone at 23 years and 167 days.
Bellingham already holds the record as the youngest player to make 50 appearances in the competition.
Liverpool seek response after league defeat
Liverpool will look to recover from Sunday's 1-0 Premier League defeat to Arsenal at Anfield when they take on Fenerbahce.
Despite the loss, coach Andoni Iraola said there were encouraging aspects of his team's performance but acknowledged the need for improvement, particularly in attacking the penalty area.
"It's difficult when you lose. But, honestly, I'm happy with a lot of things from the other day," Iraola said.
Maresca urges City to avoid costly mistakes
Manchester City coach Enzo Maresca has called on his players to eliminate individual errors following consecutive Premier League defeats against Aston Villa and Brighton.
He said mistakes had repeatedly cost his side in recent matches and stressed the importance of analysing those problems and finding ways to improve ahead of the Leipzig encounter.
Maresca acknowledged that neither the players nor the coaching staff and club were satisfied with the recent results.
PSG, Manchester United, Barcelona and Bayern secure victories
Paris Saint-Germain set a Champions League record on Tuesday by becoming the fastest team to score four goals in a match, racing to a 4-0 lead against Villarreal within 17 minutes before completing a 6-0 victory.
Manchester United produced an impressive comeback to defeat Roma 3-2 after making their worst-ever start to a European home match.
Barcelona recorded a 3-0 victory over Aston Villa, while Bayern Munich secured a 2-0 away win against Atletico Madrid.
