If Lewis Hamilton has anything to say about it, Fernando Alonso won't be joining Mercedes anytime soon.
The McLaren driver's contract expires at the end of 2017 and it seems highly improbable, at this stage at least, that the Spaniard would extend his lease at Woking.
Pundits therefore are already relishing the prospect of a move to Mercedes and a mega-battle in-house with Lewis Hamilton.
But the Brit is hardly keen on such an outlook when asked in Shanghai yesterday.
"It's not going to happen," he said.
"If you have got two kilos on either side, and then take the two kilos off and put four on, what is the point? You need the balance," he said.
Hamilton thinks the balance at Mercedes is perfectly right as it stands with current team mate Valtteri Bottas. A judgement whihc Mercedes boss Toto Wolff agrees with.
"Again here he is only two tenths behind Lewis, which is a strong performance given how great Hamilton's (qualifying) lap was," said Wolff.
"I am also very happy about how well Lewis and Valtteri work together."
Would the 'entente' be just as good if Bottas was beating Hamilton ? We hope to soon find that out...
