Real Madrid —
Gareth Bale's Real Madrid is hoping to make history by becoming the first club to successfully defend the Champions League title. No team has managed the feat since Europe's top tournament was revamped in 1992.

Barcelona —
Last season, Lionel Messi and co.'s title defense ended at the semifinal stage. The Spanish champion will be one of the favorites again this time. Luis Suarez, Neymar and Ivan Rakitic were all outstanding last season -- and don't forget a certain Andres Iniesta.

Bayern Munich —
Always in the mix, the German champion will hope to improve on last season's semifinal performance. New manager Carlo Ancelotti, who has won the competition three times as a coach, has added to his squad with the acquisition of teen midfield star Renato Sanches -- who helped Portugal win the Euro 2016 title.

Atletico Madrid —
The Spanish club suffered heartbreak in May's final -- losing out to rival Real on penalties after a 1-1 draw in Milan. It was the second time in three years that Diego Simeone's side had gone close to winning the competition. He'll be hoping France star Antoine Griezmann returns from Euro 2016 all fired up.

Juventus —
It might have lost Paul Pogba to Manchester United, but Italy's "Old Lady" is still a team to be feared. The perennial Serie A champion splashed out $99 million on Napoli striker Gonzalo Higuain in the off-season, while its impressive defensive core remains. It will be a tough nut to crack under coach Massimiliano Allegri.

Paris Saint-Germain —
The French champion reached the quarterfinal stage last season before being beaten by Manchester City. Its iconic striker Zlatan Ibrahimovic has left to join Manchester United, but new coach Unai Emery has brought in Real Madrid's Jese and Poland midfielder Grzegorz Krychowiak from his former club Sevilla.

Borussia Dortmund —
Back in the competition after spending last year in the Europa League, Dortmund will be one of the teams to fear. Its style of fast, free-flowing football has been one of the most exciting on the continent over the past year and, led by the likes of Marco Reus and top scorer Pierre-Emerick Aubameyang, it could reach the knockout stages.

Manchester City —
The English team reached the last four for the first time in its history before somewhat meekly losing to Real Madrid. New coach's Pep Guardiola first task was to bring the club through the qualifying stages. The former Bayern and Barcelona coach has already spent big on signing Ilkay Gundogan, Nolito, Leroy Sane and John Stones.
