Calculating trophy counts

Let's break down the trophies: there are six Copa titles since the 2011-12 season, but Valencia won the 2019 Copa. For Supercopa, they won four: 2011, 2013, 2016, and 2018. Barcelona won the 2023 Supercopa as noted. In Europe, they secured three titles: the 2015 UCL, UEFA Super Cup, and Club World Cup. Altogether, that’s 20 major trophies. I might have minor inaccuracies, but focusing on managerial stability might be more relevant than exact counts.Analyzing Real Madrid's achievements

The question mentioned "更迭统计分析," which suggests analyzing managerial stability rather than just trophy counts. However, I can relate the two. Since 2011, Real Madrid has won five La Liga titles, including 2023-24. They also won three Copa del Rey titles, starting from 2011. For Supercopa, I'd say they total about six since 2012. They've secured six Champions Leagues and four UEFA Super Cups, along with five Club World Cups. That's quite a lot!Summarizing Atlético Madrid's achievements and manager changes

I think I should focus on summarizing Atlético Madrid's achievements without getting too bogged down in exact counts. Since 2011, they've secured two La Liga titles, a Copa del Rey, a Supercopa, and several Europa League and UEFA Super Cup titles, totaling eight major trophies under Simeone. The question centers on manager changes, so I’ll layout a methodology for counting head coaches, excluding caretakers unless they've managed a significant number of matches. I'll create a simple bullet list for clarity, including manager names and tenures.Organizing managerial metrics and insights

I'll organize the metrics into clear bullets. First, I’ll compute important metrics like the number of manager changes, total head coach stints (including returning coaches), average tenures in months, and turnover since 2011 for each season. The insights show that Atlético is stable due to Simeone, while Madrid experienced moderate turnover but still claimed the most European trophies. Barcelona had a turbulent period from 2020 to 2024, changing managers frequently due to instability. I might include a simple ASCII timeline for clarity, focusing on conciseness.
