The Brasileirão is infamous for its revolving door of managers, but just how extreme is the turnover compared to the rest of the world? A recent study by the CIES Football Observatory has crunched the numbers, and the results might surprise you.

Over the last 12 months, a staggering 17 out of 20 Serie A clubs have changed their head coach at least once. That's an 85% turnover rate, placing Brazil among the most impatient leagues on the planet. While the global average across 55 leagues sits at 65.2%, the pressure cooker environment of Brazilian football clearly demands immediate results—or else.

At the very top of the instability ranking sits the Cypriot first division, where a perfect 100% of teams have parted ways with their manager in the past year. South America is well-represented in the top ten, with leagues in Peru, Venezuela, Paraguay, and Chile also showing a distinct lack of patience. On the flip side, Norway's Eliteserien is a fortress of stability, with only three managerial changes across all 16 clubs.

The study also looked at the age profile of these often-short-lived leaders. In Brazil, the average manager is 51 years old, slightly above the global average of 49.5. Bulgaria boasts the most experienced coaches, averaging 55.6 years, while Sweden is clearly betting on youth, with the lowest average at just 43.5 years.

CIES specialists describe these findings as evidence of "chronic instability" in world football. The constant pressure for short-term success, fueled by a culture that prioritizes immediate results over long-term planning, creates a high-stakes environment. The recent departure of Juan Pablo Vojvoda from Santos in March is just the latest example of this dismissal culture that shapes the landscape of both Brazilian and international football.
