Barcelona and Bayern Munich played out a UEFA Champions League classic, as the Bavarian giants inflicted a stunning 8-2 defeat on Quique Setien's side. In what went down as one of the worst nights in Barcelona's decorated history, Bayern Munich were rampant and sent out a massive statement of intent with a comprehensive victory.Thomas Muller opened the scoring on the night, but Barcelona restored parity as they were blessed with a massive slice of luck when David Alaba turned the ball into his own net.Hansi Flick's side took control of the game and added a staggering seven more goals, as Luis Suarez's second-half strike wasn't even a consolation for the Catalans.2015 - Luis Suárez has scored his first Champions League goal away from Camp Nou for the first time since September 2015 vs Roma at the Stadio Olimpico; he went 1,952 minutes and 69 shots without scoring at other venues.
