Goal.com posts two types of articles:
1- Those without any indication where they brought them from. You can't find the source under the article. Those articles are totally invented by that site and has no incredibility.
2- Those ended by "GD" under the articles, and those are just translations for what Gazzetta dello Sport posts.
So, yes, I don't trust the first type of those articles and don't read them at all while I make use of their translating to GD's news.
