LONDON (Reuters) - Three-time Grand Slam champion Andy Murray said he hopes Roger Federer will stay involved in tennis as he heads into retirement but suggested the Swiss great is so gifted that coaching other players might prove difficult.

The 41-year-old Federer claimed 20 Grand Slam singles titles, ripped up the record books and is widely-regarded as the best player ever to wield a racket.
