Anelka now accepts the rotation system at Stamford Bridge, a situation that would have seen him react immaturely as a young player.
"It is frustrating when you are 20 years old - when you are 32, not anymore," he said.
"Sometimes you are not happy because you want to play, but you have to understand it's part of the game and we have big players.
"You have to make everybody else happy also, and like I said, if you are 20, you don't understand this rotation.
"But if you are 32, I won't say you have nothing to prove, but you have the experience to understand.
"When you're a manager it is even more difficult than playing because you have to keep everybody happy and make choices.
"I know I won't be a manager, I don't want to do it - never!"
