Jos Buttler has plenty on his plate in his new role as England's limited-overs captain, meaning he has no plans to play Test cricket right now – whether opening the batting or otherwise.

Buttler has been appointed England's white-ball skipper following the retirement of long-term leader Eoin Morgan.

The superstar wicketkeeper-batsman was an obvious choice, having been a key performer under Morgan for several years.

Buttler's role in the Test set-up is less established, and the red-ball side are enjoying their own new era under the captain-coach combination of Ben Stokes and Brendon McCullum.

Big-hitting Buttler prides himself on being "positive and aggressive", as he told BBC Test Match Special on Friday. Those are qualities that would clearly work in Stokes' side, whose tactics Buttler described as "very similar" to the limited-overs approach of "taking the shackles off".

Debate around a Test return was perhaps inevitable then, but Kumar Sangakkara, Buttler's IPL coach with Rajasthan Royals, suggested he should be a candidate to bat at the top of the order, where England have had some difficulties.

Buttler was amused and bemused by the idea, saying with a smile: "I thought someone had written the wrong story, to be honest. I don't think there is much merit in that.

"Was it from Kumar? Maybe he was just plugging some Rajasthan Royals openers or something like that.

"It's been fantastic to watch the Test team over the last few weeks – I've thoroughly enjoyed tuning in as a fan; it's been incredible to watch.

"You're gripped to your seat to see what they're doing, and it's been brilliant. I've loved watching them, and I hope it continues."

Asked if he had a red ball in his bag, Buttler replied: "Not at the minute, no."

But while the white-ball skipper is happy to maintain a watching brief in Test cricket, he is keen to have the red-ball captain in his teams.

Stokes was named in England's ODI squad for the series against India, although he will not be involved in the Twenty20 international matches that follow a Test that started on Friday.

"I'm really keen for Ben to be involved in T20 cricket," Buttler said. "As with everyone, we're going to have to be careful with how we manage people's workloads.

"Ben's going to be incredibly busy. The first T20 starts after this game [the Test against India] is due to end. It's important we look after players.

"But in any format of the game, Ben is someone you want in your team."

Kumar Sangakkara cannot recall seeing anyone bat better than Rajasthan Royals run machine Jos Buttler in the Indian Premier League ahead of the final against Gujarat Titans.

Buttler blasted the Royals into their first final for 14 years with a scintillating unbeaten 106 off only 60 balls to secure a seven-wicket win over Royal Challengers Bangalore in Qualifier 2.

The England wicketkeeper-batter hit six sixes and 10 fours in a masterclass at Narendra Modi Stadium on Friday, taking his tally of centuries for the season to four.

Buttler is only one shy of Chris Gayle's record of scoring six IPL hundreds ahead of the final in Ahmedabad on Saturday.

The 31-year-old is the leading run-scorer in the tournament with 824 from 16 innings at an average of 58.86 and Royals director of cricket Sangakkara has never seen anything like it. 

He said: "It's hard to describe what he has done for us this season. I think he started off so well, had a little bit of a flutter at one point in the tournament, but he calmed himself down, had good conversations rather than just training.

"He accepted he's mortal, he's human and he can't have that high level of excellence every single day. And to understand how you kind of reach that level at every game in different stages.

"Some days you have to fight and look ugly, other days your rhythm is there. The reality is you can't fight that condition, but fight what's happening on the day.

"You have to settle into it and build an innings. He can accelerate at any point, has all the strokes and understands the game really well. I can't remember anyone batting this well in the history of the IPL."

Rajasthan have not reached a final since they won the inaugural IPL in 2008, when the late Shane Warne captained them to victory.

Gujarat topped the table in their first IPL season and beat the Royals by seven wickets in Qualifier 1 to move into the final.

David Miller struck a rapid 68 not out in that victory and the South Africa batter says he is reaping the rewards of the Titans putting their faith in him.

He said: "I feel like I am repeating myself. But one thing that changed this season, is that I am playing every game.

"The last four-five years in IPL… I had a bad season in 2016 and then haven't really felt backed at all. That’s the nature of the IPL. There are so many overseas players and only four can play.

"I had to go back and work on my game. Although I felt really good playing for the domestic teams in South Africa, I was looking to find that good nick. That's what happened this season."
