Virat Kohli is the latest to express his concerns about the effect of playing back-to – back series and staying in bio-bubbles, which can affect the players mentally. Kohli is currently part of the Indian Premier League bio-bubble, and soon after the tournament finishes, he will fly out to Australia along with other Indian players. “The series against Australia ends only in February, meaning that for a long time, a lot of the players will have been part of the bio-bubble culture. The Indian skipper said, speaking to a channel, a serious thought needs to be given about the length of the series for the well-being of players” Kohli said.
