The news is fake and I'm sure the recent news about Brahim Diaz replacing Salah at Liverpool is also fake. "Transfer News Live" has been dishing out fake news from their page to steer stupid debate, attract views and gain followership. Their news lack credibility. If you're looking for a reliable football media outlet, I'd recommend goal.com, skysportnews or fabrizio Romano.
This source is collecting every piece of information from various websites. It is highly likely that some of them are really fake just like you said. By the way Fabrizio Romano follows them anyway.
It is obvious Barcelona doesn't have much intention to give Fati some time to play. He continually gets injured and it lasts for a long time. Would you give him chances anyway?
He is originally a LW and can play as AM or CF in case there is such need. But looking at the players who currently play in those positions, there is no way Fati is getting the shirt from any of them.
He should find himself a decent team and start over.
