After an indifferent start to his second spell at the Bernabeu, Zidane has helped guide Real to the top of the La Liga table.
Ahead of City's clash with Los Blancos in the Champions League, Sterling has praised the Frenchman, who is attempting to lift European football's premier trophy for the fourth time as a manager.
Speaking to AS, Sterling said: "I think to win the Champions League so many times especially in a row as well is very difficult. I don't think that's luck, it's definitely a formula.
"Some people have that winning mentality and he wins by any means. So I wouldn't say that it's luck, I'd say it's something he has probably developed over his great career as a player and he´s developing his career as a manager so it continues this winning touch. I don't think when you win it's luck, it's a winning mentality."
Sterling has been linked with a transfer to Real Madrid later in his career. body check tags ::
