"It has always been about performance and has never been about age. It has become a fashion to talk about it now I think," Ganguly said here.
The 36-year-old pointed out that Sri Lankan Sanath Jayasuriya and Australians Adam Gilchrist and Michael Hussey, all of whom have scored centuries in the Indian Premier League, were over 30 years of age.
The former India captain said he was also slightly taken aback by people saying he had surprised them with his performance in the Twenty20 tournament.
"After 13 years I feel bad that I still surprise people," Ganguly said in a lighter vein.
Even 35-year-old Tendulkar, who made his IPL debut on Wednesday, said he was never concerned about the age of players."As far as I am concerned I have never entertained this theory. It is performance that matters and not age," the master batsman said.
