Stats. Yes. Because stats of course always tell the whole story.
Messi is a great player, and he's possibly the best of all time for many (just not for me).
I don't think this Argentina team has the flair, guile, or defensive solidity that some of the teams of the late 70s and 80s possessed.
Also, winning the Copa now is probably easier than winning the Asian Cup, seeing as the quality of opposition is absolutely dire. Where is the Chile team of old? Brazil are a shadow of their former selves, and teams like Paraguay and Peru have faded into obscurity in recent times. The only decent teams in South America, Argentina aside of course, are Colombia and Uruguay.
If I am being honest, I don't think this Argentina team beats Spain from 2008 to 2012, France 98 to 2002 (Thuram, Zidane, Vieira, Henry, Trezeguet), or the Italy team with Buffon, Nesta, Cannavaro, Pirlo, De Rossi, Del Piero, Totti, and Vieri.
