We should not expect players to perform the same way all the time, but we do.
But when you said that Virat Kohli and Rohit Sharma are not performing very well at the moment, I would disagree with you. Because they may have performed poorly in the previous England ODI series. But in terms of performance in the England ODI series, they have performed exceptionally well overall. So I expect them to perform well against Bangladesh, where they have been able to perform well against teams like England even I am a Bangladeshi fan but I have to accept the truths.
Moreover, apart from Virat Kohli or Rohit Sharma as their main weapon, Shreyas Iyer and Shubman Gill, there are many others.
I also agree with you. I think India has one of the most powerful names in the squad such as Shubman Gill, Rohit Sharma, Hardik Pandya, Mohammed Shami , KL Rahul, Sheryas Lyer and many other players. And in group A where we have Pakistan, Bangladesh, India and New Zealand. Bangladesh and Pakistan are not a big deal for India to face while little bit they may face a struggle against New Zealand due to their very good recent form, playing in Pakistan. This Indian dream of lifting the Champions Trophy 2025 might come true in this season.
