You won't get long balls from a tiki taka mold, Xavi and Iniesta worshipping player. But it's almost impossible to steal the ball from him, and he's very very good technically. There's no question about his technical ability, and you didn't need every player to send long balls.
Have to find out how mature he's mentally and if he'll be injury prone.
Don't expect his best anytime soon, my guess not till business end of season. Guy hasn't had preseason in two years and hasn't consistently played 90 mins for two seasons whether it's for getting frozen out/not being in Barca's plans or injuries.
