#2 Real Madrid (1931-1932) - La Liga
With 33 league titles and 13 Champions League crowns, Real Madrid are the most successful club of all time both domestically and on the continent.
Just two years after Athletic Bilbao set the standard, Los Blancos followed suit by winning their first league title in 1932 and they did this without losing a single game in the league campaign.
The capital side amassed a total of 28 points, having won 10 and drawn eight of their 18 league games (two points were awarded for a win back then) to finish three points ahead of second-placed Athletic Bilbao.
The club have maintained their success and are still one of the premier clubs in the world almost a century later. But despite spending world-record sums to bring in several world class players and managers, Real Madrid are yet to match the achievements of this illustrious side and to date, they remain the last team to finish an entire La Liga campaign undefeated.
