"All four have their own strengths and it is for the cricket board to finalise the name. I do not want to comment on the issue," Kapil, who was on a business promotional trip, said in Hyderabad on Wednesday night.
"They are very experienced and I have nothing to say on that nor do I have a name to recommend," he said.
On Ganguly's form, Kapil said: "As a skipper he did a good job and as a batsman maybe he is passing through a bad phase, he should improve and do better."
When asked what makes a good sportsperson, the 1983 World Cup winning captain of India said, "Talent, aided with good temperament brings you success."
