tata wasn't the problem. if ''best striker in the world'' aguero decides to play like dogshit, di maria and lavezzi continue their headless chicken act and higuain chokes then what can you do?
To be fair, he COULD do more than he did today. It was not a great performance from him, and we should expect more from him in such an important match. Yeah, the tactics and the play of the other Argentines might prevent him from having an absolutely dominant display, but there's something between that and his display today. Just because the rest of the team doesn't play well doesn't mean that Messi gets a completely free pass for not really performing well himself.
Hell, if he had played really well, they might've still lost, because the other attackers might have completely screwed up tons of chances he gave them or something. It wouldn't have surprised me. But that's not what really happened. He wasn't great. So yes, there IS something he could've done that MIGHT have overcome the ineptitude of players like Higuain. He could've run around more, created more magic, etc. It's not like he did everything that could be done under the circumstances.
