Benzema is questionable because he is incredibly flakey. Bale is in a different stratosphere to Hazard.
I loved Hazard when he was a young player, and I'm not saying he's not a very good player, but he's nowhere near the best players in Europe in my opinion. Too streaky, too powder puff, not enough goals or goal threat. He's just not that good. Flatters to deceive lots and lots.
