Yeah not saying economy is only factor, but mainly that Argies cant be compared to Brazilian clubs in overall because they are better off financially, its mismanagement but also poor state financially in overall (while Brazil to opposite, Mexico fairly rich too). Thats why you see Dario Conca's, D'alessandro's, Montillo's, Defederico's, Cavenaghi's and so on in Brazilian league, and not in Argie one anymore (and less and less argie stars return home, Saviola and Aimar wanted to go back to River I read, D'Alessandro too, but cant afford them even in they had big paycuts). financial difference is too clear. Dont mean River in that (and yeah know they are very mismanaged, read posts of very depressed River fans in XT), just general argentina, effects their football in a way naturally, because they have been selling players cheaper and cheaper since financial meltdown of years ago.
And yeah for it to be discussion in a football thread, you actually discuss things, its not very proudctive to just say you know better and dont say what or clarify in any way. Better to be informative then elitist, even if one knows way more indepth about a league.
