Zidane has a plethora of talent at his disposal, but its thought that some of the squad players aren't filling the coach with confidence.
Next season, Zidane wants another star attacker to join the Real Madrid front-line.
With Neymar still angling for a way out of Paris Saint-Germain, the club's hierarchy will be reluctant to lose Mbappe too.
Zidane gave Sancho five points at the Balon d'Or for the Kopa Award for the best young player of the year.
The Madrid coach is reported to be a big fan of Sancho's and believes he'd add some versatility and variation to their attack.
Zidane has reportedly asked club president Florentino Perez to 'pay what they ask' for the Englishman.
Sancho is thought to be valued at just over €100m, but Dortmund could demand as much as €140m from Real Madrid.
Madrid will face competition from Liverpool, Manchester City, Manchester United and maybe even Chelsea too now that their transfer ban has been lifted.
Sancho's popularity in his native country is no surprise considering his meteoric rise since moving to Germany.
