Does Zinedine Zidane get the credit his Champions League wins deserve?

"You don't win three Champions Leagues, two La Liga titles and 13 out of 14 European knockout ties if you are not a good manager, this is crazy."

When French football journalist Julien Laurens frames Zinedine Zidane's managerial CV like that on the Euro Leagues podcast, it is hard to disagree.

People do, though. And plenty of them.

Before this week's Champions League semi-final second leg between Zidane's Real and Chelsea – with the tie locked at 1-1 – BBC Sport examines why he is yet to win universal respect despite his achievements.
