Della Valle is good, schira no opinion on him i dont follow. morik is meh never seen him break any news or mention something against the flow/rumour windmill.
What is the obsession with breaking news dear God?
Even if one of them breaks something the others tweet 2 minutes later to confirm the news from their sources.
The most important thing for me from the reporters is that I know when they say something that is true and not made up. Not like Schira who tweets about every single player from every single league and 100 tweets a day. It's impossible to do that, to have that much information about every player. You know he's a hack just from volume. And from the fact he copy-pastes other people and then deletes tweets where he gets stuff wrong.
Della Valle broke the Vlahović news but other than that I don't remember her for anything in particular. She might have new sources from the new management based on the Vlahović thing, but she also didn't say anything about Zakaria, claimed SMS is target no. 1 over Pogba etc. Could be that she just had a source on the Fiorentina/Vlahović side so she got that right.
Albanese should just change his name to could and maybe.
Agresti doesn't have many things in advance anymore but he is one of the first briefed by the club and when he tweets something it's happening.
Romano, Di Marzio also good.
And Di Natale has been pretty good just with tidbits here and there, for example the De Sciglio renewal, still says Atalanta is buying Demiral etc.
These last 4 are who I follow. But the club in general has been very tight-lipped since last summer and it is very obvious when they brief everyone like they did with the Pogba meeting. But other than that nobody has a clue who's next in line after Pogba and Di Maria sign, if they sign.
