8 best group stage records in UEFA Champions League history

#5. Real Madrid (2011-12)

Real Madrid had great run under Jose Mourinho

Real Madrid has become synonymous with impossible records in the Champions League over the past few seasons, thanks to their dominating UCL campaigns. In the 2011-12 season, Real Madrid was under the leadership of the legendary Jose Mourinho. Although Mourinho's time at Real Madrid is viewed as a failure by many, he did manage to lead his team to achieve a perfect record in the 2011-12 Champions League season, while also winning La Liga.

Madrid's path to glory began with a group consisting of Lyon, Ajax, and Dinamo Zagreb. Mourinho, who is renowned for his tactical genius, was quick to showcase his skills during the group stages, where he deployed a 4-2-3-1 formation in all six matches and led his team to victory in every single game.

The opening game against Zagreb saw Madrid triumph with a narrow 1-0 win. Their next match against Ajax was more comfortable, with Madrid winning by 3-0. Madrid's defense was also on point, keeping clean sheets in their first two matches. Madrid then played Lyon back-to-back, keeping another two clean sheets and winning with a score of 4-0 and 0-2, respectively.

Real Madrid conceded the first goal of their campaign when they played Zagreb again, but still managed to win the match with an impressive scoreline of 6-2. The final match of the group stage was against Dutch side Ajax, where Real Madrid emerged as comfortable winners with a 3-0 scoreline, thereby achieving a perfect record in the group stage.
