The make-up of the Champions League semi-finals will be decided tonight and tomorrow as the second legs of the quarter-finals are played.
Atletico Madrid look a decent bet to knock out Barcelona, Liverpool have it all to do against holders Paris Saint-Germain, while Arsenal and Bayern Munich will fancy their chances of progressing.
Here, DAZN News reporter Ross Heppenstall picks out a key angle from each game.
Diego Simeone has been frequently linked with some top jobs in the Premier League during the past decade or so. With good reason.
The 55-year-old Argentinian has impressed hugely at Atletico Madrid since taking the reins there in 2011.
He has guided Atletico to two La Liga titles, two Europa League successes and they have been Champions League runners-up on two occasions under his watch.
Could this finally be their year? They go into tonight’s second leg against domestic rivals Barcelona with a 2-0 advantage from last week's first leg at Spotify Camp Nou.
Simeone is contracted to the Madrid-based club for another year but continues to attract admiring glances from some of England's biggest clubs.
Champions League glory this season would certainly increase his stock even further.
The likes of Manchester United, Liverpool and Chelsea are likely to be watching on with interest.
Dazn MediaLiverpool FC and famous European nights at Anfield go hand in hand, but progress tonight will take some doing.
Arne Slot’s men are 2-0 down from last week’s first leg in Paris, when they were comprehensively outplayed and fortunate not to be further behind.
The performance raised further questions over Slot’s position but, where there is life, there is hope.
Anfield will be rocking as Liverpool look to build on Saturday’s confidence-restoring 2-0 home win over Fulham and pose PSG a serious threat.
The Reds showed some welcome signs of their old selves against the Cottagers and fit-again £125million summer signing Alexander Isak could prove a useful weapon off the bench.

Arsenal have seen their hopes of silverware ended in two competitions and take a huge blow in a third during their past four games.
They lost the Carabao Cup final against Manchester City in dismal fashion before being bundled out of the FA Cup quarter-finals by Southampton.
Last weekend saw them beaten at home by Bournemouth in a massive setback to their hopes of being crowned Premier League champions.
But in the Champions League they continue to prove largely unstoppable.
Last week they went to Lisbon and beat Sporting CP 1-0 in the first leg of their Champions League quarter-final.
Another positive result against the Portuguese giants at the Emirates tomorrow would send Mikel Arteta's side into the Champions League semi-finals for the second consecutive season, marking the first time in the club's history they have achieved back-to-back last-four appearances.
It could also give the impetus needed to reignite their Premier League title bid with a huge trip to rivals Manchester City looming on Sunday.
Getty ImagesIn the fourth Champions League quarter-final, Bundesliga champions Bayern Munich will look to finish the job against Real Madrid and reach the last four.
Vincent Kompany’s men are halfway there after winning 2-1 in the Spanish capital last week with a performance that bore the look of potential champions.
Luiz Diaz and England captain Harry Kane scored the goals and Bayern followed that winning 5-0 at St. Pauli on Saturday.
That left the Bavarian giants 12 points clear at the top of the Bundesliga as they close in on retaining their domestic title.
But another powerful display against Los Blancos tomorrow night will have Bayern fans dreaming of becoming European champions for a seventh time.
