Dinesh Karthik praised Gautam Gambhir's aggressive coaching style, emphasizing that it is driven by a desire to protect and motivate his players.

He expressed confidence that Gambhir will effectively navigate this transition, as he has the acumen to understand the game's nuances. Karthik acknowledged that while Bangladesh enters the series with confidence after defeating Pakistan, playing in India presents a significant challenge. He highlighted the importance of Gambhir's support for players, noting that his aggression is always purposeful and not arbitrary. Overall, Karthik believes that Gambhir's approach will ultimately benefit the Indian team in the upcoming series.
