The problem is, you're putting too much onus on their articles. A quick scan through Reuters football articles shows that they often comment on what their sources tell them, which often turns out incorrect.
The other issue is that, this isn't putting their reputations on the line. 99.999999% of people don't even care about the Reuters article, it's just mainly people on the internet that are absolutely obsessed and dripping with desperation for Qatar to win. Their journalist even clarified that the article wasn't confirmation of anything. It was worthless, and I bet the Bloomberg article is too.
