Crystal Palace managers have the shortest ‘life expectancy’ in Premier League history, according to research collated by Opta.

Following the sacking of Liverpool boss Brendan Rodgers, only one current manager in the top flight has been in charge for more than three years.

Arsene Wenger celebrated 19 years at the Gunners last week, but the French boss is a severe anomaly when compared with his colleagues.

The current managers are averaging 2.28 years each in their jobs, but for Crystal Palace this figure is just 1.12 – the lowest of any club since 1992-93, the Daily Mail says.

Eight different managers have graced Selhurst Park with the Eagles in the top division, the average spell lasting just more than year.

That compares with over seven years for Arsenal and Manchester United, although their records are clearly blurred by the extensive regimes of Wenger and Sir Alex Ferguson.

The stats demonstrate the ruthlessness in modern football where managers are given on average 473 days at the helm, compared with 2.6 years in 1992-93.
