#2 Dani Ceballos

Ceballos was the star of the U23 Spanish squad, and was being chased by big clubs like FC Barcelona when he decided to sign for Real Madrid. Although he could have probably been a starter for the Catalan club, he choose to sign for Los Blancos because of his idol Zidane.
Since then however, we have seen very little of this talented player. He was not used even when Real Madrid rested their top stars. His lack of playing time raised doubts as to why he wasn't loaned to other clubs if he wasn't a part of Zidane's plans in a squad brimming with midfielders.
He's shown glimpses of his quality whenever given the chance, and he should depart for playing time so he develops even further. If the club aren't willing to sell - then he should preferably leave on a loan.
