Wayne probably hasn't done everything in his power to prolong his career either, especially when you have Zlatan to compare with. Scholes, Giggs, Carrick, Lampard, Xavi were all in their late teens/early twenties when they became first team regulars and have all had long careers. Pirlo made his senior debut at 16 and IMO his very best came after moving to Juventus at which point he was 32 if i'm not mistaken. I think that Tielemans with his level of technique and intelligence could have a similar longetivity to his career if he stays professional.
