England do not know their best Twenty20 side with less than a year until the World Cup, says captain Eoin Morgan.
They start a three-game series in South Africa on Friday, and potentially have a further 14 games before the tournament in India.
"There are probably seven or eight guys who are pretty strong candidates to be in our strongest XI," said Morgan.
"Winning this series would be great, but it is more important we get players roles right and they feel comfortable."
The T20 World Cup, due to start in Australia last month, was postponed by a year because of the coronavirus pandemic.
England are second in the International Cricket Council T20 rankings and a 3-0 series win in South Africa would take them move level
on points with leaders Australia.
South Africa are ranked fifth, having last won a T20 series in March 2019.
Who will open the batting for England?
Wicketkeeper Jos Buttler is set to open alongside Jason Roy, despite all-rounder Ben Stokes averaging 40.71 at the top of the order
for Rajasthan Royals in the Indian Premier League (IPL) that finished this month.
"Jos is one of our greatest-ever white-ball cricketers. He probably is the best but he's only halfway through his career," Morgan told
the Tuffers & Vaughan podcast.
Where Stokes, Morgan, Jonny Bairstow and Dawid Malan, the top-ranked T20 batsman in the world, bat is still to be decided.
Pace bowlers ready to shine
One of the areas where the series could be decided is how the fast bowlers perform.
England are likely to include Jofra Archer and Mark Wood in their side, while Chris Jordan - two short of Stuart Broad's England
record of 65 T20 wickets - and Reece Topley are also part of a 15-man squad.
Archer won the MVP award at the IPL after taking 20 wickets at an average of 18.25.
South Africa, meanwhile, have Kagiso Rabada, who won the purple cap for the most wickets at the IPL with 30, and Anrich Nortje,
who took 22 wickets and bowled the quickest delivery of the tournament.
