When his reaction was sought on the snub given to Ganguly during the auction in Bangalore, Whatmore said, "I have my personal views but I would like them to remain with me."
Ganguly, who was the leading run-scorer for KKR last year, did not find any buyer at his base price of USD 400,000.
The former India skipper did not even get a second look when 28 unsold players were brought back in the pool on day two of the auction.
KKR signed up Gautam Gambhir, Yusuf Pathan and Jacques Kallis offering them hefty pay cheques and Whatmore said it was important that stars performed.
"All the teams have great stars but we have to try and turn these into good and consistent performances," Whatmore, who coached Sri Lanka to World Cup glory in 1996, said.
The fourth edition of the Indian Premier League will begin on April 8.
