Nathan Lyon has unfinished business, and it runs through India in 2027

Nathan Lyon will be in India two years from now when Australia will attempt to win their first Test series there since 2004.

It seems more likely now that Lyon will power on till he can get his hands on an SG ball again. He is confident of going into battle with two willing and talented partners he has found.

If the 2023 Indore Test was the introduction, the 2025 Galle Test was the official coronation of what could become Australia's three-pronged trump card when they try to retain the Border Gavaskar Trophy across five Tests in India.

Lyon has taken both Murphy and Kuhnemann under his wings. Eight months before the India tour in 2022, when they were part of the reserves, Lyon made it a routine to hang around with the two younger colleagues after each nets session to work with them.

Lyon has made sure to keep Murphy and Kuhnemann in the conversation by constantly talking them up in the media.

In an interview at the start of this series in Galle, Murphy spoke about his "cool" relationship with Lyon and how much it has helped him develop.

"He wants to continue to see us young spinners develop and when the time comes, we're ready to take his place. It's a really cool relationship from my point of view. A lot of times young spinners come in and they don't have anyone to lean on. I've been lucky that every tour I've been on, Nath's been there to touch base with," Murphy said.

"Nath wants to leave spin bowling in a better place than he found it in," Murphy added.

Lyon has already enhanced and lifted the calibre and reputation of spin bowling. He has snared 546 victims and is only 18 short of going past Glenn McGrath's tally.

Now, he has a chance to really pass the torch on and also hang around for a little bit longer to see it burn brighter in the hands of his successors.

"We're three totally different bowlers with three totally different mindsets as well. I feel like I'm learning off Todd and Matt, and I feel like they're pushing me to try and get better as well. Hopefully I'm passing on a little bit of knowledge here and there," Lyon said.

While Lyon made his own impact, finishing with seven wickets, Kuhnemann proved to be the real hero of the show for Australia as he starred with a nine-wicket match haul.

Kuhnemann showed in his multiple spells in the first Test about how much he's grown as a spinner. Three of his nine wickets came on the back of him being hit for a boundary, exactly a ball later in fact. It showed an added sense of courage along with the much-needed temperament in these parts to hold your own and trust your strengths to get you wickets.

Murphy is the more classical understudy to Lyon, set to take over from him as the premier spinner of the team once he quits.

Though Murphy was used more in the third spinner's role at times in the first Test, you could see the trust Steve Smith the captain had in him.

What it does do is take away the over-reliance on Lyon in the subcontinent, which has been a load he's had to carry throughout his Test career. He's rarely had the same partner at the other end for more than two tours, having to repeatedly adjust to new make-ups and partnerships. Till the time Murphy and Kuhnemann jumped aboard. Now, he can start plotting the journey to conquer India once and for all with his two trusted cohorts, and potentially get his hands on the one major prize he hasn't been able to get his hands on: a Test series win in India. More reason why he will be in India in two years' time, and he'll be better prepared and readier than ever before.
