He is not a dribbler itself, but can surpass players with his technique but he doesn't do that a lot he use passes to move forward with the ball and without it. Hazard can dribble 2 or 3 player and make a cross to the area, if needed Aranguiz will appear to make the cross to the area. PASSING: he is good in passing, he doesn´t risk the ball, he won't make fantasy passes, and is not as talented as Cesc in this area, but is more than capable to left Costa or any other player alone into the area to shoot or to create spaces.. RANGE: if for range you mean how much field he can cover, well almost all the field, he is a box to box player, as I said he is not explosive but he can be close to the area and then appear to the other side without a problem. He will keep a constant rythm in to the match. VISSION: as I said before, he is a tactician, so he read the game well, usually he is aware of all his teammates, his range of passing is usually short and middle range but can launch long passes for counterattack. COMPOSURE: 5/5 he is not naive and at the beggining he must be lectured at how the refferees at Premier act, but I never saw him loss his composure, you hardly see any expression on his face during a match, fully concentrated all the time and have the mental strenght to compite everytime. DRIBBLING: he can dribble, but is not his best attribute, because he hardly needed due his style of play, Hazard like to surpass players with dribble, Aranguiz appear, dribble what he had to dribble if he had, and then move to the next position. STRENGHT: despite the size he is strongh enough to deal with bigger players. He can resist normal charges well, he know how to use his body to steal the ball and keep the rythm all the match. He is not a defensive midfielder like Mikel (keep him or buy a another specialist) but can be a good complement to Cesc, Matic and Hazzard. I hope this help and I know I flatterd him a lot but don't missunderstand he is not a World class player yet, but he can be. He is not the best in anything, however he is far above average in all the categories you asked me, but 1 or 1,5 steps behind WC players like Cesc or Hazzard. I believe Mourinho can push him in that direction because Aranguiz is smart and can glue defense and offense. in Chile we have Sanchez with his freak stamina and speed, Vidal with his crazy strengh and Aranguiz and his brain, he is not a flashy player if you have to create a phrase for him that would be something like: the job must be done.
