It's completely not biased to say Hazard has more potential. Spurs fans would think it is but look at the facts. Bale as Spike said, is not a World class 'Footballer' but still a great player due to his Pace, Power and Tremendous shooting/finishing. Hazard IS a fantastic footballer with Messi-eque dribbling at times, also blessed with lightning speed, agility, superhuman/insane Balance and wonderful vision. Now when he adds that finishing aspect to his game he'd be the complete package, which is why I say he could be the perfect Hybrid of Ronaldo and Messi whereas I don't think Bale will ever improve the Footballing side of his game because he simply...can't. He strays more towards the Ronaldo pathway. Hazard already has the shooting ability. It's not like he'd have to come up with this ability from nowhere. We've seen he can be a very good finisher when he tries for goals; he's scored some crackers. So all in all, Bale tremendous but Hazard will be something even more than tremendous. He'll be terrifying.
