Despite a blistering start to his managerial career at Real Madrid, the biggest tests are yet to come for Zinedine Zidane.
The Frenchman has been fortunate that in his opening few fixtures as custodian of the hottest seat in Spanish football, he hasn't had a great deal to worry about, with the greatest of respect to Los Blancos' opponents.
However, neighbours Atletico loom large in just a couple of weeks.
If leaders Barcelona manage to win their three games in the meantime and Real should lose the Madrid derby, it will put Zidane's side 10 points behind Barca with an El Clasico at the Camp Nou still to play.
Such a set of circumstances would almost certainly rule Real out of the league title race and leave just the Champions League as their only route to silverware this season.
How well will one of Real's legends then be received by his people? Will they still back him to the hilt or will the white hankies come out for him too?
It would be incredibly sad for Zizou if he were to be subjected to such treatment because, frankly, Florentino Perez has thrown him to the wolves.
Winning is expected, losing isn't an option.
But for a manager with no experience at the very highest level in Spain, that's a ridiculous undertaking. A manager who didn't impress at reserve team level either.
Club legend or not, the next three months are crucial to Zidane's long-term aspirations in the job.
