To add to the proof of this - Liverpool has a much smaller payroll than other teams in the EPL and way lower spending threshold, and yet, apart from the odd season, has vastly outperformed the other teams (bar Manchester City who are a juggernaut and managed by possibly the greatest manager to have ever lived). They are routinely held up an ultra smart and brilliantly run football team, defined by their use of data and analytics.
They currently have three of their best players running down their contracts. Two of them are two of the best players to have ever played for the club, and the fans cannot understand why they are not signed up already. One is 33, the other is 32,
The patterns are the same, they're just having much more success with Liverpool than the Red Sox. And there's still Liverpool fans that want them out of the club (due to not spending enough in their eyes and ticket prices).
