#1 Zinedine Zidane

Zidane has been both an extremely successful player and manager. Having been a legendary player for Real Madrid and France, he took over the role of Madrid's manager after the sacking of Rafa Benitez on January 4, 2016.
Having won 3 successive Champions League titles for Madrid and La Liga in 2016-17, Zidane established himself as one of the most successful managers in Real Madrid's history. He popularized the 4-4-2 diamond formation and gave chances to several youngsters at Madrid.
Having resigned 5 days after Real Madrid's most recent Champions League victory, Zidane will be the most suitable candidate to manage Spain due to familiarity with the players and the tactical nous that brought him success at Madrid. He has the ability to make Spain invincible in world football again.
