Ashes 2021-22: Buttler intent on Test cricket commitment with England despite Australia thrashing
Buttler declared he would play without fear ahead of his first red-ball series Down Under but has since mustered just 96 runs from the opening three outings, averaging just 19.2 against Pat Cummins' relentless bowling attack.
The wicketkeeper is not the only England batter to have struggled, given Chris Silverwood's side have already succumbed to a series defeat against Australia before a ball has even been bowled in the penultimate Test in Sydney.
After Quinton de Kock announced he was hanging up his South Africa whites to focus on his young family and limited-overs cricket, questions were raised whether the multi-format Buttler would follow suit and arrive at a similar conclusion.
But 31-year-old knocked back those suggestions on Saturday as he expressed his commitment to the longest form of the game, despite England's beleaguered Test team struggling recently.
He responded to reporters questioning his plans to continue playing red-ball cricket: "It's certainly my ambition. I don't think I'd have put as much into it as I have done if it wasn't.
"I have fantastic family support – they're very supportive of me and my career, and make a lot of sacrifices for that. It's certainly maintained my drive and ambition to try and play [Test cricket]."
He added: "That's Quinton's own personal situation. As a huge fan of his, I'm disappointed that he's at that stage. I love watching him bat, keep wicket and play Test cricket.
"I commend him for making a decision that's right for him. But I feel I've got that support and in a place where I want to try to make it work."
Amid speculation over Silverwood's future following another thrashing to the old enemy Australia, Buttler and his team-mates now have the chance to prove their worth in the final two Tests in early January.
And Buttler reassured that all of the England camp are pulling in the same direction as they look to play for pride with their series out of their reach.
"One thing is we're massively in it all together," he continued. "We live it all together and we want to play well for each other. It's frustrating for Chris he's not here with us [due to COVID-19] – another complication of the tour – but we're certainly very united.
"There is an overriding sense of disappointment and frustration with the situation we've found ourselves in. We certainly don’t want to be a team to lose 5-0."
England have a chance to right some of their wrongs when they next challenge Australia on Tuesday at the Sydney Cricket Ground.
