Canada - Rumours are growing by the day that the works McLaren-Honda partnership is doomed.
Failing to deliver
It seems the final straw for the British team was Montreal, where Honda failed to deliver on a promise to upgrade its woefully unreliable and under performing power unit.
Then, Fernando Alonso retired within sight of the team's first point of 2017.
Team boss Eric Boullier said: "It's difficult to find the words to express our disappointment, our frustration and our sadness.
"It's simply and absolutely not good enough."
Once a believer in Honda's potential, key team driver Alonso's message in Canada was that while McLaren is ready to win, the Japanese marque may never be.
He said: "After 16 years, it doesn't change my life to win a point or not, but we have to start scoring for the work that the mechanics do day and night, changing many engines."
So after the new engine did not arrive in Montreal, perhaps it will be ready for Baku next weekend.
A frustrated figure
The Spaniard told the Movistar broadcaster: "I do not have information about the improvement of the engine, I do not work for Honda and I'm not an engine designer."
Alonso is also quoted by Blick newspaper: "I am of course frustrated, but especially at this time for McLaren, who always give me a top car which is then attacked by everyone on the straight."
