Chelsea chairman Bruce Buck has defended their hair trigger sack policy.

Buck has been chairman since Roman Abramovich's takeover in 2003, with the Russian oligarch's reign coinciding with great success, despite managerial turmoil.

Buck said: "I know we have fired what most people would say are a lot of managers - terminated the relationship is a better way to describe it - but we've always thought long and hard when we've done it.

"It's always difficult, it's always sad when a relationship is terminated.

"We don't look back, we always look forward and see where we're going and figure out how we get there.

"We certainly believe in stability in managers, but it has to be with the right manager."
