Real Madrid want to sign Hazard, Hazard wants to join Real Madrid and Chelsea's owner Roman Abramovich is looking forward to sell the Belgian attacker, according to a report by Jugones. That's mainly why Los Blancos will sign Hazard for around €25 million, if that same report is accurate.
Hazard is clearly underperforming this season, so much that he has been in and out of the starting lineup. It would be reasonable to assume that Chelsea would like to make more money of his transfer, however, so take this report with a grain of salt for the moment.
Even if Hazard ends up playing for his idol Zinedine Zidane, Real Madrid will have to sell at least one attacker out of James, Isco and Cristiano Ronaldo to make room for the Belgian attacker. He likes to play on the left wing and that's one position that Real Madrid have covered right now.
