#4 Real Madrid
Los Blancos will be looking to make history this season by defending their UEFA Champions League title, winning it for the fourth consecutive time.
The Spanish giants surprisingly lost their Champions League specialist - Zinedine Zidane who resigned five days after guiding them to their 13th Champions League, a third consecutive victory for Los Blancos.
Despite a turbulent start to the season, Real Madrid now looks like a stable team able to compete against top European sides.
The loss of 5-time Ballon d'Or winner, Cristiano Ronaldo, in the summer could reduce their firepower in the competition, but the emergence of Brazilian youngster, Vinicius Junior, could give them hope of proceeding further.
Real Madrid's Champions League experience could play a big part in their title defence as they are always motivated in the competition.
