Lille attacker Salomon Kalou says the success of Chelsea boss Jose Mourinho is due to his straight talking.
He says the key to Mourinho's success is his honesty with his players.
He said: "Every man who plays under Jose could never say, 'Jose promised me this but then did something else'.
"Jose is always honest to his players. Whether you play or not, he's always someone who will tell you the truth. If you deserve it he will give you it, if you don't, he won't. That's what players respect about him.
"Since I signed for my first year in Chelsea he told me, 'if you work hard you will always be in my team'. And I always was in his team because that's what he said. You have to work hard to be in his team. Whether it was in the first minute or last in a game, I'm still going to make the run he asked me to because you know if you do it, it's what you're going to get because he's a man of his word."
