Former Chelsea winger believes there is only one man in charge at Stamford Bridge - and it is not Roberto Di Matteo.
Everything
Kalou added: "He always made sure whatever we needed we had it and you cannot ask more from an owner than what he did for us. He always brought the best manager and players to the club, and he helped everyone to win something.
"That's the only thing that matters because at the end of the day I look back at Chelsea and say 'I won everything'.
"I won whatever a player could expect to win, so that experience was the best experience of my career and any other player would dream of having that experience at any other club."
Kalou worked under a number of managers at Chelsea including Mourinho, Ancelotti and Guus Hiddink and admits it was not easy with all the chopping and changing.
"Personally I think it's better to have stability," he added. "Some clubs have an identity with the way they play like Manchester United, Arsenal, Barcelona, because they keep their coaches for so long.
"With Jose we had that but when Jose left, it was kind of difficult to have that again because we kept changing managers.
"That was hard for players but, because we were together for a long time and we knew each other so well, we could adapt to the situation.
"But for me it was especially hard. Every time I got to the level where I had convinced a manager that I should be in the team and play regularly, the manager got sacked. So then you have to go back to the beginning when a new manager comes in.
"You have to convince the new manager all over again and when you do convince him, he gets sacked. You go through the same emotion every season and you think it's never going to happen for you."
