Real Madrid are allegedly unhappy with the weight of big-money signing Eden Hazard.
Since moving to the Bernabeu from Chelsea in the summer, Hazard has failed to impress, with just one goal coming from six appearances in all competitions.
The Belgian's transition from the Premier League to La Liga has partly been hindered by an injury sustained during the final days of pre-season.
However, according to reports in Spain, members of the Real coaching staff feel that the 28-year-old still needs to lose weight over the coming weeks.
Los Blancos are said to want the playmaker to shed approximately 4kg in order to improve the level of his performances at the Bernabeu.
