Karun Nair scored a plethora of runs in domestic cricket, and it paved the way for his comeback to Team India after eight years. Nair, however, hasn't done justice to his return and failed to score big in the England series. In six innings, Nair got plenty of starts but failed to score a single fifty. He has scored just 131 runs at an average of 22.

Former BCCI selector Devang Gandhi and ex-India wicketkeeper Deep Dasgupta cast doubts over Karun Nair's future in Test cricket. Gandhi highlighted a major technical flaw in Karun Nair's batting which is costing him his wicket. He added that the flaw can be rectified, but said that it might be too late for him to make adjustments now.

“If you watch closely, Karun's front foot is still in the air at the point of release from a fast bowler,” Gandhi was quoted by Hindustan Times. “That delay makes it harder for him to go back or forward quickly, especially against faster bowlers like Archer or Carse.”

“He’s doing the hard yards, playing over 30 balls in almost every innings, but lapses in concentration and technical timing are costing him,” he said.

“He needs an earlier trigger movement. That’s fixable, but at his age, it’s not easy. Adapting to different triggers for different bowlers is another option, but that takes time and high-level skill.”

Deep Dasgupta also echoed Gandhi's sentiments and said that the team should start investing in Sai Sudharsan.

“You have to look at the bigger picture,” Dasgupta said. “Karun is almost 34, and Sai is just starting out. If you’ve identified Sai as someone who could be part of the Test setup for the next decade, then he needs to be playing in these conditions now."
