#4 Barcelona
Barcelona makes an appearance on our list this week, knocking off this season's upstarts from Leipzig, courtesy of superior numbers and the force of nature that is Lionel Messi.
La Blaugrana have painfully watched from the sidelines for years as their arch-rivals in the Spanish capital snagged every Champions League trophy in sight, causing unrest at the Nou Camp as Messi and his band of merry world beaters grew unsatisfied with just domestic domination.
At the start of last season, Messi voiced his intent to bring back the big-eared trophy to the Nou Camp, however, last season's campaign turned out to be a false start. Eventual winners Liverpool proved to be the stumbling block, as they sensationally knocked Barca out.
Barcelona have secured qualification to the knockout stage, bagging their 149th win in Champions League competition, thanks to a beautiful 3-1 win over Borussia Dortmund in Catalonia.
Messi was at his best once again, as he marked his 700th appearance for Barcelona with a goal and two assists. His deft pass provided Luis Suarez with the opener before he scored his 613th Barca goal a few minutes later. La Pulga capped off a wonderful performance with another incisive pass to Antoine Griezmann for Barca's third goal of the evening.
Barcelona march on to the knockout stage with European domination at the back of their minds and an unbeaten record in tow. La Blaugrana faces Inter Milan next, but top spot in Group F is a foregone conclusion.
