Inter shocked as Bayern and Madrid win openers

FC Bayern München and Real Madrid CF opened their UEFA Champions League group stage campaigns with away victories, but 2010 winners FC Internazionale Milano suffered a shock home defeat by Trabzonspor AŞ in the second set of matchday one games.

Undoubtedly the most eye-catching of Wednesday's results came at San Siro. Trabzonspor enjoyed a night to remember on their UEFA Champions League bow as Ondřej Čelůstka struck with 14 minutes remaining to give them a famous win against Inter.

Goals in either half from Toni Kroos and Rafinha gave Bayern, whose Fußball Arena München home hosts this season's final, a solid opening win at Villarreal CF in Group A. However, it was less of a straightforward night for nine-time European champions Madrid, who squeezed past GNK Dinamo Zagreb – back in the group stage after a 12-year absence – 1-0 and had to hold on after Marcelo's second-half red card.

Runners-up last year, Manchester United FC came from behind to earn a point at SL Benfica, Ryan Giggs cancelling out Óscar Cardozo's effort. FC Basel 1893 have the early lead in Group C after they defeated FC Oţelul Galaţi 2-1 in a game which finished with both teams down to ten men. PFC CSKA Moskva came from two goals down to nick a point at LOSC Lille Métropole, while AFC Ajax and Olympique Lyonnais played out a goalless draw.
