Messi is the greatest player in history, says Thiago Silva

Melbourne, May 1: Reclaiming the top spot in Test cricket has brought smiles back on their faces but Australia coach Justin Langer says beating India in their own den remains the ultimate test and their numero uno status will be put to test when they clash with the Virat Kohli-led team.

After a tumultuous transition phase post the ball-tampering scandal, Australia on Friday displaced India as number one side in Test format but Langer is aware that it does not take long for the situation to change.

"We recognise how fluid these rankings are, but at this time it was certainly nice to put a smile on our faces," Langer told Cricket Australia website. "We've got lots of work to do to get to be the team that we want to be, but hopefully over the last couple of years not only have we performed well on the field, but also off the field," Langer added.

The former left-handed opener underlined what he felt will be the ultimate test of character.

"Certainly a goal for us has been the World Test Championship ... but ultimately, we have to beat India in India and we've got to beat them when they come back (to Australia).

"You can only judge yourself as being the best if you beat the best and we've got some really tough opposition to come," Langer put his priorities in place. The team he insists needs to get better as now others will come gunning for them.

"Getting to No.1 is a great thing, but when you're No.1, you're always the hunted," Langer said. "We've been the hunters for a while, now we're the hunted and we need to get better and better."

Langer also hoped that white ball team under Aaron Finch will win the World Cup. "I know how hard it is to win World Cups ... everything has to go right. One day, I'd love to see Aaron Finch with all his mates lift that T20 World Cup above his head."

May 4: Yuzvendra Chahal is among the best leg-spinners in international cricket right now but he can be more effective with better use of the crease, says former Pakistan spinner Mushtaq Ahmed.

Ahmed picked Chahal, Australia's Adam Zampa and Pakistan's Shadab Khan among the top leg-spinners in white-ball cricket.

"Chahal as been impressive. He is definitely among the top leg-spinners of the world. And I feel he would be more effective if he uses the crease a lot more," Ahmed said.

Ahmed, who has coached all around the world and is currently a consultant for his native team, said India's ability to take wickets in the middle-overs in the limited overs format through Chahal and Kuldeep Yadav has been a game-changer for them.

Both the wrist-spinners were brought into India's limited overs set-up following the 2017 Champions Trophy. Though, of late, both Chahal and Kuldeep havn't been playing together.

"He (Chahal) can go wide of the crease at times. You got to be smart enough to understand pitches. If it is a flat pitch, you can bowl stump to stump," said Ahmed, one of the best leg-spinners Pakistan has produced.

"If the ball is gripping, you can go wide of the crease because you can trouble even the best of batsmen with that angle. That way your googly also doesn't turn as much as the batsman expects and you end up taking a wicket."

Chahal has taken 91 wickets in 52 ODIs at 25.83 and 55 wickets in 42 T20s at 24.34. He is not a huge turner of the ball but uses his variations very effectively.

Ahmed also feels the likes of Chahal and Kuldeep have benefitted immensely from former captain M S Dhoni's advice from behind the stumps.

"You have got to be one step ahead of the batsman. You should know your field position as per the batsman's strength. I always say attack with fielders not with the ball. If you understand that theory, you will always be successful," the 49-year-old, who played 52 Tests and 144 ODIs, said.

"India has become a force to reckon with in all three formats as it uses its bowlers really well. Dhoni was a master at getting the best out of his bowlers in limited overs cricket and now you have Virat Kohli."

He also said the art of leg-spin remains relevant more than ever.

"You need leg-spinners and mystery spinners in your team as they have the ability to take wickets at any stage of the game. I see a lot of them coming through in the next 10-15 years.

"Most batsmen now like playing express pace but with a good leg-spinner in the team, you are always in the game," added member of the 1992 World Cup-winning squad.

Sydney, Mar 29: Steve Smith's two-year leadership ban ended quietly Sunday, leaving him eligible again to captain Australia at a time of uncertainty over when international cricket will resume.

Smith was stripped of the captaincy and banned from leading Australia for two years over his involvement in the 2018 ball tampering scandal in South Africa. His sentence ended Sunday and he can again captain Australia if called upon.

Australian players were due this week to conclude a series of matches in New Zealand and, for some, to join the Indian Premier League. But it wasn't clear Sunday if the IPL will take place this year and when international matches will resume. Australia's scheduled mid-year tours to England and Bangladesh are in doubt.

Smith told Channel Nine television's Sports Sunday he is doing his best to stay mentally and physically fit, training in his home gym, going on 10 kilometer (6 mile) runs and practising the guitar.

"It's obviously not looking likely (the IPL will go ahead) at the moment," Smith said. "I think there might be some meetings over the next few days to discuss what the go is with it all.

"I'm just trying to stay physically and mentally fit and fresh and, if it goes ahead at some point, then great. And if not, there's plenty going on in the world at the moment. So just play it day by day."

It seems unlikely Smith will return to the captaincy when cricket resumes. Tim Paine is firmly established as Australia's test captain and at 35 is not immediately considering retirement. Aaron Finch has captained Australia successfully in white ball cricket.

The conclusion of Smith's ban ends the period of upheaval in Australian cricket that followed the ball tampering incident in the second test at Cape Town in 2018 when Cameron Bancroft, with the knowledge of Smith and his vice-captain David Warner, used sandpaper to change the condition of the ball.

Smith and Warner received one-year bans from international and most domestic cricket and Bancroft was banned for nine months. The scandal also resulted in the resignation of coach Darren Lehmann and the departure of Cricket Australia's chief executive, James Sutherland.

Warner remains under a career-long leadership ban.
