The Senegal international does feel he owes something to Benitez, who leaves his post as interim boss after this weekend's friendly against Manchester City in New York.
Ba, speaking at a Chelsea youth soccer clinic in Harlem, said: "It's been good since I came and he (Benitez) has been good.
"He made good rotation between me and Fernando.
"I have had the chance to play a lot of games since I came and that has been really good.
"I have learned a lot, about new team-mates and the way Chelsea plays football. I'm very happy."
