Premier League holders Chelsea play Qarabag in Baku, Azerbaijan on Wednesday night seeking to progress from Champions League Group C.
Here, Press Association Sport looks at some of the talking points ahead of the contest.
Taking care of business
Win and Chelsea will be in the knockout stages. Even a draw will be enough if Atletico Madrid drop points against Roma, who enter the fifth round of matches one point better off than Chelsea.
Chelsea beat Qarabag 6-0 in September, but the Azerbaijan side have since pushed Roma close and twice drew with Atletico. Chelsea, meanwhile, claimed one point from two games with Roma.
Securing a place in the last 16 with one game to spare, even if first can still be contested, will ease Blues’ minds.
Since losing 3-0 at Roma, Chelsea have beaten Manchester United 1-0 and West Brom 4-0.
The Blues have four straight Premier League wins since the defeat to previously pointless Crystal Palace.
Antonio Conte’s side have veered from the sublime (at Atletico Madrid) to the spineless (at Palace) this season and must show greater consistency, no matter the occasion or opposition.
Luiz to get a chance?
David Luiz was an integral figure in Chelsea’s title triumph in Conte’s first season, but his star has fallen this term.
Necessity saw the Brazil defender moved forwards into midfield in October’s 3-3 draw with Roma, but Conte admitted the experiment saw Chelsea’s approach change, for the worse. And after the 3-0 loss in Rome, with Luiz in a crumbling defence, the Brazilian has been a spectator.
Not even on the bench against United, he was an unused substitute at West Brom, but he may get his chance in Baku, not least to give the impressive Andreas Christensen a breather.
Baker’s dozen of games
Qarabag is the first of 12 games before the end of the calendar year and 13 (a Baker’s dozen) if you include the January 3 clash at Arsenal.
The congested schedule makes rotation necessary and Saturday’s trip to Liverpool may be on Conte’s mind when it comes to team selection in Baku. He must get the balance right, though, as Chelsea must maintain momentum.
Conte often references that he used just 13 or 14 players when Chelsea had just a domestic focus last season. Now his more peripheral men must show they too can perform.
Morata and Eden are Hazard-ous
The pair can become a devastating partnership to rival any in the European game – but they must keep producing.
With Cesc Fabregas’ artistry and N’Golo Kante’s industry, Chelsea have players the envy of many of their rivals. It is about their team-mates rising to the occasion, like they did last season.
Sevilla’s Argentine coach Eduardo Berizzo has been diagnosed with prostate cancer, the club confirmed on Wednesday, just hours after his side staged a remarkable comeback against Liverpool in the Champions League.
“The medical services of Sevilla FC can inform that the coach of the first team, Eduardo Berizzo, has been diagnosed with an adenocarcinoma of the prostate,” the club said in a statement.
“Further tests will determine which steps to follow regarding his treatment. Sevilla FC wants to show their full support to the coach right now and wishes him a speedy recovery.”

Berizzo, 48, made no statement on his health when speaking to media after the Spanish side came from 3-0 down at half-time to draw 3-3 against the five-time European champions.
A former centre-back for River Plate, Marseille and Celta Vigo among others, Berizzo is in his first season as Sevilla boss after three successful years in charge of Celta.
Several Sevilla players had hailed Berizzo’s powers of motivation to orchestrate their second-half fightback.
“We had to come out with a different attitude for the fans and for the boss, he made us play like that,” said Argentine international Ever Banega. “He turned the situation around in the second half.”
Spanish football has rallied round Berizzo with numerous clubs, including his former side Celta sending their support.
“All our strength and support for Berizzo,” the Galicians posted on Twitter.
“Be strong boss, you are in the best place in the world to not give in because there they never give up,” said Sevilla’s legendary former sporting director Monchi, who joined Roma earlier this year.
Sevilla sit fifth in La Liga and need just a point from their final Champions League group game away at Maribor to secure their place in the last 16.
It remains to be seen whether Berizzo will need to take time away from his duties as coach to concentrate on his recuperation.
In the 2012/13 season, then Barcelona coach Tito Vilanova stood aside for several months as he underwent treatment for throat cancer in New York.
Vilanova returned for the final two months of the season as Barca won the league with a club record 100 points, but resigned shortly afterwards and passed away in April 2014 at just 45.
Awful news that Sevilla manager Eduardo Berizzo has prostate cancer. But to hear he told his players about it at half-time, 3-0 down against Liverpool, and they rallied to draw 3-3, is an example of the power of sport. Good on them

Sevilla produced a stunning fightback from a three-goal half-time deficit to earn a thrilling 3-3 draw with Liverpool on Tuesday thanks to Guido Pizarro’s stoppage-time equaliser.
Roberto Firmino scored twice as Jurgen Klopp’s side looked set to qualify for the knockout stages for the first time in nine years and seal top spot in Group E with a three-goal blitz in the first half-hour, with Sadio Mane also netting.
However, Wissam Ben Yedder pulled two goals back before Pizarro stabbed home from a corner to protect Sevilla’s year-long unbeaten run at home.
Here are two good and two bad performances from the exciting clash in Spain.
There was a time when Firmino wasn’t considered an out-and-out striker in the traditional sense. That may still be true, but he scores some traditional centre-forward goals quite often these days, along with his reportoire of smart finishes and thunderous strikes.
On Tuesday, his movement allowed him to ghost in unmarked at a corner, and then he scored in front of an open goal for his second.
WISSAM BEN YEDDER
Ben Yedder has been somewhat of a Champions League specialist for Sevilla this season. He came into this game with four goals from four appearances in Europe this season.
Two more on Tuesday to bring Sevilla from 3-0 down to 3-2 takes him to six, the same as Tottenham’s Harry Kane. Only Cristiano Ronaldo has scored more.
His first was a world-class header, even if it came largely thanks to some awful static defending from Liverpool.
Supposedly, Alberto Moreno has improved defensively this season. If that’s true, then someone forgot to remind the Spaniard, because he came out after half-time looking every bit the error-prone left-back who loses concentration too easily and gets caught out too often.
Moreno was at fault for Sevilla’s first two goals, failing to see Ben Yedder’s run to the near post for the first and then giving away the penalty for the second.
At least he can’t be blamed for the equaliser that completed Sevilla’s comeback – he’d been hooked long before that.
While not directly at fault for any of Liverpool’s goals, Geis did not give a good account of himself against Liverpool’s high-flying attack.
Part of that was down to Sevilla’s midfield largely being invisible in the first half, leaving Geis and his fellow defenders exposed, but there were times when he looked like a deer caught in the headlights, not knowing what to do.
The German, who is on loan from Schalke, is rumoured to have caught the eye of some of Europe’s leading clubs but on this evidence he still needs improvement.
