Root's future as England captain in doubt after West Indies rout

Joe Root may be "passionate" about remaining as England's Test captain but should he stay in the post after the West Indies inflicted the latest damaging defeat of his tenure?

In January, the 31-year-old star batsman insisted he wanted to begin the process of helping rebuild England's red-ball fortunes by continuing to lead the team in the Caribbean following their humiliating 4-0 Ashes series loss in Australia.

But a thumping 10-wicket defeat in the third and final Test against the West Indies in Grenada on Sunday condemned England to a 1-0 series loss after two draws.

Root has now overseen just one win in 17 Tests and has failed to lead England to a series victory in his last five attempts.

Nevertheless, he insisted Sunday: "I am very passionate about taking this team forward.

"I feel like the group are very much behind me. I know this is a results-based business but it does not feel like we are far away from turning results."

And after five years and a record 64 games in charge, a decision on Root's future as skipper might well have been made for him by now.

But following the Ashes debacle, the England and Wales Cricket Board (ECB) sacked both their managing director Ashley Giles and coach Chris Silverwood, with fellow former Test players Andrew Strauss and Paul Collingwood taking over on an interim basis.

Until the leadership vacuum at the top of the ECB is filled, and given England's next Test is not until June, when they face New Zealand at Lord's, Root will stay on barring his own resignation.
