Isco finally decided to stay with Real Madrid even though he is not an undisputed starter, and coach Zinedine Zidane is the man behind Isco's determination.
While the player's inner circle wanted to see him gone and playing relevant minutes elsewhere, Zidane talked to him and convinced him of staying, explaining that this will be a very long season for Real Madrid where he will have plenty of chances to play and prove he deserves a spot in the starting XI. In fact, Real Madrid could play almost 60 official matches this season if Los Blancos do well enough in the Champions League and the Copa del Rey.
It's true that Isco will probably have to do perform at a brilliant level if he wants to sit Casemiro on the bench, given that Toni Kroos and Luka Modric are undisputed starters for this team. However, the Kroos-Modric-Isco midfield worked with Carlo Ancelotti and could work again with Zidane if the Spanish midfielder has what it takes to take Madrid to the next level.
