Kalou insists that Drogba remains one of the best strikers in the game and their close relationship could reap dividends for the Blues on the run-in.
"Every time I have the chance to work with him I listen to what he has to say - he is very important to me," said Kalou.
"When you're talking about strikers in the game today, Didier is one of the best and I want to take advantage of this opportunity to learn from him.
"Didier is like a big brother to me. First of all we come from the same country and that makes us closer.
"He still takes me to one side at training and gives me tips. We are always working in front of the goal. He is always so sharp in front of the net and I want to improve that side of my game.
"I can improve and develop every season by playing with him. Didier this year has been very important for the club, like every year.
"He has an amazing goal-scoring record for Chelsea and as a player it is a level I want to reach. I'm taking it step by step but I am trying to get in the team regularly first."
