Jucilei is probably your best bet mate he is still on 22 (at the start) 25 now and he develops with better facilities and coaches
some of the players may not have developed as nicely as that though, also look at Vincent Pajot, Sissoko, Macdonald Mariga, Kwadwo Asamoah, Lars Bender is a machine at 25 Vidal, Casemiro, Taras Stepanenko, Vitsenets....
