Technically that should be in the - non-yet-created - Transfers and Rumours 2020-2021 thread. Unfortunately, while I have been considering creating one I'm… sort of... too lazy…
( also think the person posting about it should be someone with the technical ability to post stuff from Twitter, coz… that was one strange way to announce it!
Actually, if you just copy the Twitter link in your message, it will automatically show the tweet, so that is really, really easy and not like posting an image, which I for the life of me can't understand why should be so difficult/not be a manual for.
