As someone who followed Memphis for years, he's definately more like Bale/Ronaldo than like Hazard.
He
can leave behind 3 defenders in a small space but he's more comfortable in beating 1 or 2 with speed and flair. That's what he's best at, when he has some space in front of him.
He's a teamplayer and not egoistic, he'll pass or cross if he thinks he can't beat what's in front of him. His right foot is deadly, he can curve balls from anywhere within 30 meters of the goal and he will do this. This makes him so good (or frustrating, if you're a pessimist).
His selling point for me is that he has no real weakness. He can do everything and the things he's not good at he is improving at an alarming rate. His decision making isn't perfect yet, but compared to the Memphis of 1.5 years ago he looks a completely different player. He's so much more complete and he's only 21. He's already very strong too so he doesn't get shrugged off the ball like most young wingers.
At 30m, for what I'm seeing now, I think that he's definately worth it. He may turn out like crap, but I believe that he will be a star whereever he goes. I'd be heartbroken if he goes to Liverpool. Will he become the next Ronaldo? You never know, he has everything to become it though. At the very least he'll become a good winger for a club like Everton.
