As regards to his World Cup,all good players need good players around them to bring out the best in them ( Think Pele and Brazil ) Argentina have been fairly poor of late and have underachieved ! Now with Barcelona we see how good he really is because no player can do everything on their own. Now he doesn’t often pick the ball up in his own box and go on a solo run to score but he does have a knack of turning nothing into something when receiving a half decent ball ! I have seen a lot of good players in my time of watching football ( 40 yrs ) since I started to fully take it in and I still think this kid is way ahead !!
I agree that Argentina have been poor, but it’s not through lack of quality players. They have Higuain, Milito, Mascherano, Tevez, etc.
I also agree that Messi is probably the best ever, but I maintain he needs to prove it at a international level. If only because he was poor a the last World Cup. Mind you their Manager might have been partly to blame. ;)
