Alastair Cook said it was the right time to stand down as England cricket captain after feeling he could no longer give the role his all.
Cook ended his tenure yesterday after more than four years and a national record 59 Tests in charge of England.
The 32-year-old looked jaded on England's last Test assignment in India, where they were beaten 4-0, including back-to-back innings defeats in the last two matches.
Cook's reign featured successive home Ashes victories, while he can also boast series wins as captain in India and South Africa.
On the flip side, his tactical acumen was often called into question while England suffered a whitewash defeat to Australia Down Under in 2013-14, followed by a shock loss to Sri Lanka at home.
Joe Root is a strong favourite to replace Cook but director of England Cricket Andrew Strauss yesterday refused to anoint the Yorkshireman as the only contender for the position.
