"Zaheer became very dominating over Rahul last year through the IPL.
It is not a crisis point, but a gentle reminder is needed that Zaheer is there to bowl and Dhoni to captain,
" said Crowe, who was the chief cricket officer of the Bangalore outfit.
"It is only with regards to general gameplan and field placements at any given moment that I am raising this point," Crowe wrote in his column for a website.The former New Zealand captain took strong exception to Zaheer's tantrums on the field and said,
"Zaheer Khan has quite a lot to say on the field. Dhoni needs to be very careful with players like Zaheer who is getting too vocal and animated, otherwise it will start compromising with his own leadership.
"The New Zealander drew a parallel with Rahul Dravid, who was leading the Bangalore Royal Challengers in the inaugural edition of the Indian Premier League and said the former India captain often had to compromise on the field due to Zaheer's antics.
