Rumours are BCCI is planning for the T20 series against South Africa and New Zealand before the T20 world cup.
I hope Jadeja comes back and provide this team with more balance.
The IPL is going to run for two months starting from April. And the T20 World Cup is scheduled for October. Therefore the BCCI has enough time to schedule one or two bilateral series during the gap between the two events. I am doubtful regarding New Zealand, because the government has prohibited the national team to tour foreign nations due to the COVID 19 pandemic. However, inviting South Africa sounds like a good option.
