If Australia's Test and T20I teams played on the same day, what would the XIs be?

In the era of Covid-19, the cricket calendar will need be redrawn and there will be a crush to fit in all the fixtures that were deferred. It has even been suggested that two formats could be played at the same time. While that may not actually happen, it throws up some intriguing selection questions.

If we consider playing a Test and a T20I on the same day, West Indies would probably have the fewest selection headaches, given they already have very different five-day and limited-overs squads.

Tests: Kraigg Brathwaite, John Campbell, Shai Hope, Darren Bravo, Shamarh Brooks, Roston Chase, Jason Holder, Shane Dowrich, Rahkeem Cornwall, Kemar Roach, Shannon Gabriel.

T20Is: Chris Gayle, Lendl Simmons, Shimron Hetmyer, Rovman Powell, Nicholas Pooran, Andre Russell, Kieron Pollard, Dwayne Bravo, Oshane Thomas, Sheldon Cottrell, Sunil Narine.

But how would the three best-resourced sides in the world - England, India and Australia - fare in having two teams play at the same time in a Test and T20I?

Australia have already gone down the path of picking two separate international teams, when, in 2017, the T20I side took on Sri Lanka at home while the Test team was in India. We asked recent selector Greg Chappell and former batsmen-turned-commentators Michael Hussey and Brad Hodge to pick two squads of 12 for the challenge. The idea is to treat the matches as equally important and pick the best balanced squads.

Greg Chappell: My focus was to get the best team for both formats. Obviously Smith and Warner could fit easily into each, as could Starc and Cummins. I must admit I was not prepared to weaken the Test team to bolster the T20I team. Both teams are competitive in my view. And, to me, Cameron Green is the next superstar of Australian cricket. He is a genuine prospect with bat and ball, but I think his future is as a batsman who can offer some quality overs. Cameron is a batsman of rare talent. At 6ft 7in, he could become something very special. I would bat him at No. 6 to start with, but I reckon No. 4 is his long-term position. The sooner he gets to play at this level, the sooner he will become the player that he should be. He has proven that he can make runs at the first-class level, so the sooner he can prepare and play alongside Warner, Smith and Marnus Labuschagne, the sooner he will work out what he needs for the highest level from these champions.

Michael Hussey: The process I went through was: I wrote down the Australian Test No. 1-12, then a T20I 1-12, and I put the players in that are definitely Test and definitely T20 players. With the gaps, I tried to find the right balance in a team with players who were maybe just outside the squad. David Warner was a tough one because he'd be a first pick in both the Test and T20I teams, but I wasn't that confident in the other openers in T20. I know there's D'Arcy Short, but I just thought Usman Khawaja was too good a player not to have involved, so that's why he's at the top of the order in Tests. Steven Smith in the middle is probably more effective in Test cricket, although very effective in T20s as well, and then Mitchell Starc is a tough one as well. His ability in white-ball cricket, particularly with the new ball and at the death in T20s, is just so good. I felt I could cover him in the Test team with the likes of James Pattinson, Josh Hazlewood, Pat Cummins - more sort of Test specialists. It wasn't easy, but two pretty good teams, I reckon, and hard to beat.

Brad Hodge: I thought Warner was irreplaceable in the Test side given his record opening the batting and averaging 50 is substantial, even though he has an unreal T20 record. I felt you could still replace him - you might not get the same output, but you'll get something close to it with Marcus Stoinis or Chris Lynn up the top. If you took him out of the Test side, I think Australia are completely vulnerable to the new ball. Khawaja, I didn't put him in just because he's been dropped, and Nic Maddinson has scored a pile of runs in the last two years of Shield cricket and deserves a chance. With Stoinis and Moises Henriques, I went for more experience - taking Smith out of that XI along with Warner - ahead of Short and Mitchell Marsh.
