Barça isn't Madrid- the style isn't about buying the "top" players in the world, then trying to find a way to mash them together into a team (rinse and repeat). The Barça brand is technical team football- players who have fantastic control of the ball and work together to create team goals. My point was simply that Reus has a skill set that is a far better fit than Neymar's (and Neymar would have been a much better fit at Madrid, where counterattack plays a more prominent role and there is the space to support Neymar's "swashbuckling" skill set). Neymar is young and talented and can learn (as did Alexis, who was vastly improved as a Barça player in his last season). And, of course, Neymar clearly has tried to learn to play more "Barça-like." But he is simply a sloppier player, because Barça-type precision has never been necessary for him to excel before his move here.
Neymar should just take an example from Iniesta and work on perfecting his croqueta, far more useful and successful than all the other flashy stuff he tries (and mostly fails with against superior defenders than he faced in Brazil). His short passing game will improve with time, as did Alexis'.
