Elano fast?? no... he's a good player but he's very slow
Danilo is the best RB I've seen in Santos for the last years... he's RB but he can also play with left foot... you can see his goal in the Libertadores final against Penarol he scored with left foot... but the most beautiful goal of the Libertadores goal was also by Danilo with left foot... take a look in the first goal:

he's very good in defense as well but his best thing is offensive... he has scored other goals as well last year in Brazilian Championship but have never seen him taking freekicks as we have Elano and Ganso to do it...
