This is a very similar situation to the one that surrounded Red Bull’s former head of strategy, Will Courtenay, who is now McLaren’s sporting director.
It emerged at the 2024 Singapore Grand Prix that Courtenay had signed to join McLaren when his contract ended, and Red Bull emphasised that he would not be allowed to leave before 2026.
They did not specify exactly when in 2026, and BBC Sport has been told that negotiations were held that led to him starting work at McLaren on 1 January this year.
Despite that, for the entirety of last year, Courtenay stayed in his previous role, even though Red Bull were fighting McLaren for the drivers’ championship.
For now, the same thing will happen with Lambiase – he will continue in his role as Red Bull’s head of racing and race engineer to Verstappen for the foreseeable future.
However, just because Red Bull’s statement announcing his departure said he would not be joining McLaren until 2028 does not necessarily mean that will be the case.
McLaren’s statement said Lambiase would join “no later than 2028”. That means they will be hoping to come to an agreement with Red Bull that shortens that timeframe.
It’s worth pointing out, meanwhile, that McLaren have emphasised that Lambiase is joining to provide support for team principal Andrea Stella, not ultimately replace him.
Stella has until now been fulfilling the role to which Lambiase has been appointed, that of chief racing officer, in addition to that of team principal.
Stella said last week: “Zak (Brown, the chief executive officer of McLaren Racing) and I have built a flat team structure, in which it is essential to ensure all leaders are properly empowered, but at the same time, we must guarantee there is always the necessary level of long-term support.
“It goes without saying that, with this approach, the dual role I currently hold could not be sustainable in the long run.”
McLaren have indirectly – but very clearly – rejected what are said to be inaccurate reports that Stella is on his way to Ferrari.
Stella said in a statement issued by McLaren on Friday: “Some of the recent rumours, including those regarding astronomical salaries and mythical pre-contracts, have made me smile.
“It almost seems as though the ‘silly season’, which usually begins before summer, has arrived early!
“I’m quite used to this sort of thing by now and I take with a smile. It almost looks as if some envious pastry chef has tried to spoil the preparation of a good dessert at the McLaren patisserie. However, we do know very well how to distinguish the good ingredients from the poisoned biscuits.”
