For example Massimo Di Culo and Gianluca Momblano.
In England, I ignore anyone that is writing for The Sun, Daily and Sunday Express, Star, Metro, HITC (and any other online blogs driven by advertising) unless they are quoting direct sources. Also ignore social media 'gurus' or 'ITKs' as they won't be any quicker off the mark than the genuine media, unless maybe by 30 mins or so.
BBC, Telegraph, Times, Independent. Named writers and not 'sports reporter'. These tend to verify their sources before publication, and will also tell you if it's conjecture or not.
I also know of about four very reliable Spurs-focused journalists, who would get thrown out of press conferences and/or have their privilege of insight removed by the club if they started making shit up.
I assume Juve also has a close circle of journos who the club trust to 'leak' information?
