#4 Dani Ceballos
The Spaniard joined Real last summer from Real Betis, having flourished in the u21 European Championships and being named Player of the Tournament too. Barcelona were also interested in his services, though he rejected their advances and opted for the defending champions instead.
However, things have certainly not gone well for the 21-year-old as he's struggled considerably for minutes at Real this term. Only managing five La Liga appearances to date, three of those were off the substitutes' bench.
Philippe Coutinho's big-money switch to Barcelona last month has left a creative hole in Liverpool's attacking system, one which some reports have suggested could be filled by Ceballos' presence.
Zinedine Zidane himself admitted that the 21-year-old has not featured regularly enough and given how his progression has stagnated with limited first-team football this season, it's becoming increasingly possible that he'll angle for a move away in the summer.
