Not yet but there are rumours that Honda has accepted to go to Toro Rosso and announcement would happen Wed or Thu.
here there is the link to article with rummours http://www.marca.com/motor/formula1/gp- ... b461e.html
And here an article analizing who wins and loose from the deal https://as.com/motor/2017/09/11/formula ... 21944.html
To my eyes it would be the most stupid move from Mclaren.
They will become a costumer team and loose Honda Money.
There are not gurantees Alonso will continue.
And Redbull could finish if Honda improves next year the only biggest winner, Honda money and exclusive deal looking at 20121.
Bloody good job! hopefully Mclaren would not regret this decision
