McLaren have confirmed the signing of Red Bull's head of aerodynamics Peter Prodromou.
Early Saturday rumours began swirling that a 'key figure' in Red Bull was set to join McLaren though at that time nothing had been confirmed.
Now though both McLaren and Red Bull have made the news official: "He's signed a contract with us," McLaren's Martin Whitmarsh told Reuters at Suzuka.
Soon after his Red Bull counterpart Christian Horner said: "We've enjoyed a long relationship with Peter and he's a valuable member of the team and there's quite a duration left on his contract," he said.
"We won't force him to stay, if it's his choice to leave then he'll leave at the end of his contract. But we are quite some way off that," Horner added.
Indeed it is thought Prodromou's contract with Red Bull runs until the end of 2014 meaning he will not be able to start until 2015.
The man who broke the story, Auto Sport und Motor's Michael Schmidt described Prodromou as the "right hand man" to Red Bull's chief designer Adrian Newey and "one of the best engineers in F1".
Schmidt added: "The move would be remarkable, because it is the first time in a long time that Red Bull has lost one of its key figures."
He continued explaining "good pay" and high bonuses for championship successes are why high level departures from the Milton Keynes based team are rare.
The impact of Prodromou's move on Red Bull will take some time to be felt though certainly it is a major blow to Red Bull's design team and a major boost for McLaren entering it's next Honda era.
