5 things to watch out for as Real Madrid play Juventus in the UEFA Champions League quarter-final 2nd leg

#3 The tactical battle - Zidane vs Allegri

Tactical geniuses at work - who will come out on top?

Zinedine Zidane will be remembered by football fans around the world as one of the finest midfielders to have graced the game. Not many expected Zidane to bring instant success to Real Madrid when he took up the managerial reigns from Carlo Ancelotti in January 2016.

Since then, he has converted Real Madrid into a complete team. Real have won two Champions League, UEFA Super Cup and Club World Cup titles.

Zidane's playing style is based on fast, free-flowing and attacking football that is a delight to watch, considering the quality and depth in attack that Real Madrid possess. High pressure and crossing when the opposition is defending deep, are Zizou's major tactics.

On the other hand, we have Juventus's manager Massimiliano Allegri who has superbly developed the team that he inherited from Antonio Conte. Juventus has become the 'talent cultivation pool' of Europe with stars like Dybala, Pogba and Morata rising to prominence in the recent years.

Allegri is an absolute genius in managerial terms because of the way he tinkers with the formations in times of need. He is a really good motivator, and can bring out the best in his players whenever required so. He will be looking to spring a surprise or two against the current champions tomorrow.
