The Manchester United striker has emerged on the radar of Blues boss Jose Mourinho and although his future appears to be at Old Trafford, Hazard says the reigning Europa League champions would be buoyed by a possible arrival.
"Rooney would be a brilliant signing," Hazard said. "He's a great player who has the experience and he's still only young, at 27.
"He's got a few years left to play. But it's not up to me. It's not my decision."
