San Claudio Bravo
They all deserve blame. Messi was their best player but he could have done more, was below his normal level.
You continue to say he could have done more, but Argentina did not play well in the tournament, played specially awful in the final, key players AGAIN under-performed and failed, and Tata Martino was exposed once more as tactically inept.
To expect Messi to do more, to excel and play at his bests for every game, something he doesn't do even at Barca, it just strikes me as very unrealistic and unfair.
