Carlo Ancelotti has said "the problem [Eden Hazard] has right now is he has a coach who prefers another player."
Hazard was an unused substitute in Sunday's Clasico.
Ancelotti picked Vinicius Junior and Rodrygo on the wings at Camp Nou and was rewarded when both were involved in David Alaba's opener.
"The problem [Hazard] has right now is he has a coach who prefers another player," Ancelotti said in a news conference on Tuesday ahead of Madrid's LaLiga game with Osasuna. "That can happen in a squad like Real Madrid's. What's important is the player has the motivation to work to play. He is doing that."
