Sir Geoffrey Boycott criticised England’s lack of preparation for their continuing World Cup woes but spared captain Jos Buttler of the bulk of the blame.

Buttler accepted his future was out of his own hands as England crashed to an eight-wicket defeat to Sri Lanka in Bengaluru, which has left the defence of their title hanging by the thinnest of threads.

Head coach Matthew Mott has written off England’s chances after four defeats in five games, which Boycott argued was the result of turning up in India just over a week before the campaign began.

“History shows that England rarely bat well in India where the ball spins,” Boycott told the Daily Telegraph. “Our guys are okay on flat pitches but if it turns they have a problem.

“The best way to try and overcome that would have been for our squad of players to get to India early and play four or five warm-up matches. What did England do? Plan only two warm-up games with one getting rained off. Not smart planning.”

England brought eight of the 2019 trophy-winning side with them to the subcontinent but Buttler has been unable to get the best out of his charges – as Eoin Morgan spectacularly did four years ago.

But Boycott feels the unflattering comparisons between the duo are unfair, pointing out Morgan had home comforts plus a fully-focused and healthy side in peak form whereas Buttler has had several obstacles to contend with.

Boycott said Jofra Archer’s non-availability and Ben Stokes being ruled out of the first three matches through an ill-timed hip problem complicated matters for Buttler.

“Jos has a dysfunctional squad of players,” the England great added. “Poorly selected, poorly prepared, not a settled team, many not sure of their roles, patchy form, confidence wobbly and to cap it all England’s best two and most influential white-ball players have not been available.

“Although Buttler has admitted his own flaws this tournament, too many people are criticising his captaincy and judging him against that of Eoin Morgan when England won the previous World Cup.

“Make no mistake, not having Archer is huge alongside Stokes not being available through injury for the first three matches. Reece Topley has now had to go home injured.

“It is easy captaining a good team full of in-form players but it would need a miracle man to pull this team together. Buttler can’t admit it, but it must be a nightmare.”

Former England captain Sir Geoffrey Boycott has called on Australia to issue “a full public apology” for the controversial stumping of Jonny Bairstow at Lord’s.

Bairstow was dismissed in bizarre circumstances as the tourists won the second Test during a tense final day, with Australia wicketkeeper Alex Carey throwing down the stumps after the batter ducked the final ball of the over and set off to talk to partner Ben Stokes.

The wicket was upheld by TV umpire Marais Erasmus, who judged that the ball was not dead, but Bairstow clearly felt the over had been completed once he made his mark behind the crease-line.

The incident drew a furious reaction from the fans in attendance, who booed and jeered for the remainder of the day, while there were even angry exchanges as Australia passed through the Long Room.

England skipper Stokes suggested he would have reversed the appeal and one of his best known predecessors, Boycott, backed him up in typically forthright fashion.

“Australia need to have a think about what they did and make a full public apology,” he wrote in the Daily Telegraph.

“That way it will redress the situation and everyone can move on. These teams have played brilliant cricket in great spirit and it is a shame when something like that happens to spoil it all.

“Australia have now had time to think about what happened. We all make mistakes in the heat of the moment. People will think better of the Australians if they put their hands up and say “we got it wrong”. That is the way to go. Let’s see over the next few days if they are man enough to do that.

“If you want to win at all costs then cricket should not be for you. We want people to play hard and fair but surely there are standards to uphold? When batsmen are not trying to take an advantage then you should not follow the letter of the law. Apply some common sense.”

Justin Langer, the former head coach who took charge of Australia’s last two Ashes campaigns, lined up on the opposite side of the debate.

He praised Carey for being alert to the opportunity and suggested Bairstow was guilty of leaving himself vulnerable.

“Alex Carey has been criticised, unfairly in my opinion. His wicketkeeping has been supreme and he is also a man of impeccable character,” Langer told the Telegraph.

“Bairstow’s dreaming should not come back on Carey. Not for a moment. Quick thinking under pressure was the antithesis to Bairstow’s lack of awareness. In my opinion, there is no way Australia were looking to breach the spirit of the game. They have learned from past experience that there are no winners in this.

“In this case perhaps the spirit of the game has been breached by the same people who are throwing stones and reacting without any recourse.”

Not everyone’s opinion on the subject tallied directly with their nationality, with former Australia international Brad Hogg unimpressed by the incident.

The 52-year-old, who played seven Tests and 138 limited-overs internationals for Australia, told talkSPORT: “I was disappointed from the start, I thought they should have called Bairstow back.

“He wasn’t taking any advantage. At the end of the day it’s not a good spectacle for Test cricket.

“England, for me, were hard done by. You don’t want to win a Test match by taking cheap wickets like that. It’s not the same as a stumping, not the same as running someone out batting out of their crease. He was in his crease (when facing).

“He did the same act a number of times at the end of the over beforehand, Australia should have warned him if they were going to do this.”
