LONDON — After André Villas-Boas became the fifth soccer manager to lose his job in the 20-team Premier League this season, The Daily Mail offered a salutation to Tim Sherwood, who was named this week to replace him at Tottenham Hotspur on an interim basis as the club hunts for a big-name successor.

“Welcome to the madhouse,” the newspaper said.

The admonition was not only for Spurs, who have fired eight managers in the past 12 years. A total of 195 managers have been fired or hastened into resignation since the Premier League began play in 1992, on the way to becoming the financial juggernaut of European sports, with nearly $5 billion in total club revenue in the past three playing seasons alone.

What has become known in Britain as the managerial carousel extends even further, across the 92 clubs that make up the top four divisions of English soccer, including the Premier League. According to organizations that track the firings, those clubs have since 1996 racked up more than 800 firings among head coaches and managers. (In Britain, the terms are interchangeable, referring to posts whose occupants run a team’s on-field operations.)

For soccer fans, 1996 has become a benchmark for the type of hand-wringing that has accompanied the Villas-Boas firing. That was the year Arsène Wenger arrived in England. Now 64, Wenger, with 17 years at the helm of another London club, Arsenal, is the longest-serving manager in the Premier League and a counterpoint to the revolving door of management that prevails at many other clubs. After several lean years, Arsenal is at the top of the Premier League standings, followed closely by Liverpool, Chelsea and Manchester City.
