Chelsea owner Roman Abramovich has approved new manager Andre Villas-Boas' clearout of his inherited staff.

The National says Bryan English, the medical director; Paul Clement, the assistant first-team coach; and Glenn Driscoll, the fitness coach, all left Chelsea after meetings with Ron Gourlay, the chief executive.

English was thought to have not been helpful in the prompt return to action of Michael Ballack, Michael Essien and Frank Lampard.

Driscoll drew Carlo Ancelotti's ire last season by questioning the players' workload as the manager engaged in extra tactical work. Clement was regarded as surplus to requirements under Villas-Boas.
