One source with connections to both Chelsea and Monaco described the night as one in which the clubs involved had "played with fire and got burned."
The saga began with Chelsea preparing the ground for Enzo Fernandez's £125million departure to Manchester City by targeting Camara as his midfield replacement, only for Monaco to insist the 22-year-old was going nowhere at the price Chelsea were willing to pay.
"I've been speaking to them for the last 10 days," Scuro said. "At around 16:00 BST yesterday we got contact from Chelsea. The answer was the same: no."
Instead, Monaco allowed Folarin Balogun to fly to Merseyside to complete a £40million move to Everton, with Camara, according to the French club, having agreed to stay put. With three hours left in the window, Chelsea appeared to have accepted their midfield business was done, having also failed with an enquiry for Roma's Manu Kone.
Everton's medical issues with Balogun then reopened the door.
"Of course, Chelsea saw an opportunity," Scuro said. "Monaco need money, Balogun is struggling there, let's go and try. Chelsea called us and said: 'Maybe we can be the solution.' At that moment, we had to open the door to discussions."
Talks resumed with Monaco at 20:00 BST and a £47million fee was agreed shortly afterwards, with Chelsea completing all necessary paperwork and Camara passing a medical and signing a contract until 2033.
But Everton, having failed to find alternatives to Balogun, revived their own move with minutes remaining.
"What happened was that around 22:00 BST our time, maybe a bit earlier, Everton realised there was no issue and decided they were ready to sign the contract," Scuro explained. "As soon as we received that information, we came back to Chelsea and said there was no deal. Because that's also fair. It's part of the game."
Chelsea were left furious, saying Monaco informed them of the collapse in writing rather than by phone, while Monaco believed a deal sheet signed five minutes before the deadline for Balogun's transfer had secured the sale they needed to help meet Uefa's financial regulations, having raised €106million of a required €150million from player sales this summer.
