After a complete sweep of domestic trophies, Barca strengthened their squad with the signings of Joan Garcia and Marcus Rashford in the summer as they look to improve on last season's semi-final elimination from the Champions League last season. Many of their rivals, however, have made significant changes, too, with Bayern splashing out on Luis Diaz and Nicolas Jackson.
City, meanwhile, have replaced key players like Kevin De Bruyne with Tijjani Reijnders while Rayan Ait-Nouri and Rayan Cherki were also brought in. Madrid are off to a strong start in La Liga under new coach Xabi Alonso and hope to seal Champions League glory in his first attempt. The Spaniard has a new squad in hand and is still figuring out their best side, with almost everyone at risk of being dropped.
Despite these improvements, Ballack sees only two top contenders to win the prize this season, giving his backing to Lamine Yamal-led Barca and PSG.
