1. Bayern Munich
Expert view - Florian Bogner, Eurosport.de:
Carlo Ancelotti is putting something together that Pep Guardiola couldn’t: peaking in April/May, not in the autumn. With the 5-1 win against Arsenal in the first leg of their last-16 tie, Bayern turned on the power switch for this season, playing efficiently and dominantly. They are unbeaten now for 18 games. The key is the use of an old system (4-2-3-1, remember Jupp Heynckes) with two holding defensive midfielders (mostly Alonso/Vidal) which gives them more balance against the good teams. Plus: Thiago is emancipated from Guardiola, Lewandowski scores more than ever and Hummels is on his way to Beckenbauer-esque glory. On the minus side: key players like Alonso (35), Lahm (33), Ribery (33) and Robben (33) are over their peak and Muller has lost his mojo.
Top scorer: Robert Lewandowski (7)
Star man – Thiago Alcantara: The only thing stopping Thiago’s ascent to greatness since he moved to Bayern in 2013 has been a ruinous run of injuries but he has started seven of eight games this season and is instrumental to the way Ancelotti’s team play. Only two players have completed more than his 582 passes – Julian Weigl (600) and Steven N’Zonzi (644) – and he has also contributed two goals and two assists. No one can run a game with the ball at his feet as well as break through the lines with a well-timed dribble quite like Thiago.
Key stat: Bayern have completed the most passes of any team in the competition, with 5,497 at a pass completion rate of 92%. They also have by far the highest average possession of 66%; Barcelona are the next closest with 62%.
Odds to win: 3/1

2. Real Madrid
Expert view – Jorge Ordas, Eurosport.es:
Despite having been without Gareth Bale due to injury for three months, they lead La Liga by two points, with a game in hand, and have won a lot of matches. Maybe they are not as powerful as in other seasons (neither are Barca or Atletico), but Real Madrid and the Champions League are historically good friends. And when they are in trouble, they have a magical solution: Sergio Ramos after the 85th minute… In terms of weaknesses, they do not have an impressive defence with their opponents scoring at least one goal in 13 of their past 15 last games.
Top scorer: Karim Benzema (5)
Star man – Sergio Ramos: The automatic answer is always Cristiano Ronaldo but he has been eclipsed by Benzema in the goalscoring stakes this season, even if only Neymar, with eight, has more than his six assists in Europe. Ramos has emerged as the true talisman of this team in recent months though, with a succession of late and important goals. He has also scored in two of the past three Champions League finals; it is fair to say he has a taste for the big occasion, as well as a tendency to attract red cards…
Key stat: Real Madrid have won or drawn 16 games when coming back from a goal or more down, in all competitions.
Odds to win: 4/1

Expert view – Simone Eterno, it.Eurosport.com:
You probably already know Juventus' numbers: the winning streak in home league matches (31); just one defeat in all the European clashes played at Juventus Stadium; the best defence in the Champions League. Numbers aside, there’s the strength of a team that, while less entertaining than in recent seasons, are adaptable to any tactical solution: three midfielders, two midfielders and the ‘Four Stars’ (Cuadrado, Dybala, Mandzukic, Higuain) and so on. This is also probably the last year of the legendary defence with Buffon, Barzagli and Chiellini, and Gonzalo Higuain has brought to the team the ‘pure striker’ that Juventus have been missing since David Trezeguet. So everything seems to be working perfectly with the Bianconeri, who finally look like a team with the necessary confidence to have their say in Europe, as well as Italy.
Top scorer: Gonzalo Higuain (3)
Star man – Paulo Dybala: He took on his shoulders the heavy legacy left by Tevez and Pogba. Paulo Dybala is not only the new star of Juventus, but the key player from which all of Juventus’ offensive game plan starts. You can often see him dropping between the lines to retrieve the ball; you can see him creating space and numerical superiority. Do not be fooled by just two goals scored until now in the Champions League – if there is a player more dangerous than than the rest, it's Paulo Dybala.
Key stat: Juventus have conceded the fewest goals of any quarter-finalists, with just two in eight games.
Odds to win: 8/1

Expert view – Jorge Ordas, Eurosport.es:
Luis Enrique will leave Barcelona after this season and nobody knows how the story will unfold over the next three months. Barca’s presence in the quarter-finals is an unexpected gift after the miracle against PSG. This game could change their mentality and make them more powerful. As a weakness, despite the fact Neymar, Suarez and Messi are always at a top level, Barca’s midfield is not the draw it once was. Xavi has left, Iniesta is 32 and Busquets is having maybe his worst season. Furthermore, new players as Andre Gomes, Arda Turan, Paco Alcacer and Denis Suarez have not improved the team.
Top scorer: Lionel Messi (11)
Star man – Lionel Messi: Cristiano Ronaldo might have the Ballon d’Or but Messi is the best player in the world and he has reinforced that impression with another stunning European campaign. He is just as liable to start a move from deep than he is to finish it off these days, but Messi remains almost unstoppable with the ball at his feet. Neymar’s miraculous performance in the 6-1 second leg win over PSG hinted at his coming supremacy, but for now, Messi is still king, at Barcelona and elsewhere.
