Shreyas Iyer's attitude problem.

Guys,i used to like Shreyas Iyer,i used to think he deserves capataincy of ODI and so on but with time i have realised it that he has some attitude problems, the humbleness is missing. If you see Rohit and Virat, they have a class, and their class is visible in their behaviour. But i find that class missing in Shreyas. Whats your take ?
