Okay, so I've had some snippets from a reliable source a couple of times, and I've just heard from him now.
Ederson was obviously at the CFA this week, signed his contract, and completed his medical - and is now back in Portugal. While everything is agreed between City and Benfica, there are still some third party issues which needs to be resolved before we can announce him as our player.
The announcement should be on Monday, if everything goes to plan - if not earlier. At the absolute latest, the announcement will be on September 1st. 110%.
Don't shoot the messenger.
