Messi is 24 now so next world cup 27 than next 31 and the 3rd word cup 35-36? maybe he will retire from international football=P but good luck anyway=)
Easy enough?! Win 2 World Cups (1 to catch Maradona 1 to emulate) with Argentina to end an old then write a new chapter in their respectful football history!
Messi vs Maradona
Maybe you will be the difference?! <)
