I'd say that marchisio is better than what DDR was at this age but only time will tell if he becomes as good I guess
Umm, NO WAY, not even close (to being better, having similar progression is somewhat similar though). Marchisio is 23, DDR was great when he was 23, part of the NT squad for a while (in contention since age 20), playing in the WC, all in all a somewhat proven player.
Marchisio progression is quite nice, but hardly better then DDR 3 years ago. We can only hope Marchisio becomes as good, let alone better, for that to happend, he is ALOT to do and accomplish.
I find Marchisio very promising and couple of years off of being a nice top player ala Chiellini progression, but De Rossi's highest level is ridicolously high. Its very optimistic of us to think he will reach that absolute world class level, lets see what he has in store, so far quite promising.
