Joe Root should be asked again if he truly wants to stay on as England captain, according to former skipper Michael Vaughan.
As England toiled in the early stages of day three of the third Test against West Indies, Vaughan said England and Wales Cricket Board (ECB) chiefs should sit down with Root after the series in the Caribbean.
The ECB is advertising for an England men's team managing director, but Vaughan says a priority should be the captaincy.
England's bowlers struggled to make inroads in the latter stages of West Indies' innings on Saturday, allowing Joshua Da Silva to reach a maiden Test century and the hosts to open a 93-run first-innings lead.
Vaughan questioned the vitality of the England players, a number of whom are still carrying scars from the team's 4-0 Ashes drubbing.
Interim managing director Andrew Strauss said after England's Ashes calamity that Root was "absolutely clear" he wanted to keep the captaincy. However, Vaughan thinks the time has come to ask again.
"I think the biggest meeting first and foremost is to sit with Joe Root, and really look him in the eyes and say, 'Have you got the energy?'," Vaughan said on BT Sport.
"There comes that moment as England captain that the energy is not with you. You're still going out there, you're still trying your best, but you've not got the energy. If he has got the energy, then I would stick with him. But if he's lost that energy and the real drive and that desire… As a captain, you have to wake up every morning and it's got to be your love, captaining the England side.
"If you've lost that ounce of any kind of loving it, you've got to give it up. If he's lost that desire and love to captain England, just be the batter, because he'll score as many runs, and he'll still be a great leader in the side.
"I can see an England captain that looks a little bit drained."
Vaughan said of England's morning performance, as West Indies advanced from 232-8 to 297 all out: "It looked an England side, and England captain, that looked very, very tired."
He praised the home team's efforts in frustrating the tourists, but added: "I'm pretty sure there'll be a lot of England fans out there watching the telly, throwing things at the screen and thinking, 'I could do a lot better than that'.
"It was just a little bit of a lack of imagination. It concerned me a bit about the skipper this morning, I didn't think he tried enough, didn't try himself early enough."
Part-time spinner Root eventually brought himself on to bowl and took the final wicket, having Jayden Seales caught and bowled.
"As a captain in those kinds of situations, you've got to be so energised, you've got to be on your bowlers, you've got to be on your team, you've got to be creating ideas, creating angles," said Vaughan. "I didn't see enough of that this morning."
Root's difficult day got worse after lunch when he was caught at slip for five off Kyle Mayers to leave England 27-2 in their second innings.
