Ferrari team chief Mattia Binotto had every reason to read the riot act on Monday after the Italian team handed an unexpected triumph to Lewis Hamilton and Mercedes in Sunday's Russian Grand Prix.
As he reviewed events at the Sochi Autodrom and scanned Italy's reaction to Ferrari's largely self-inflicted defeat, Binotto may also have felt a chronic driver headache coming on.
Ferrari have developed the fastest car but it is Mercedes and Hamilton who are heading for the titles again.
The classic partnership of old master, in the form of four-time champion Sebastian Vettel, and young pretender, Charles Leclerc, has been heating up all season as Leclerc outperforms his venerable teammate.
On Sunday, it boiled over from a sporting duel into a more fierce and personal rivalry.
The dispute, or misunderstanding depending on your viewpoint, cost Ferrari a victory and a probable one-two and handed both prizes to their rivals as Hamilton came home ahead of Valtteri Bottas.
Vettel, who benefitted from a slipstream provided by Leclerc on the opening lap to take the lead, defied team orders by ignoring instructions to let the younger man go by -- arguing that he would be threatened by Hamilton if he did and adding that he had taken the initiative with his own speed.
Many critics on social media accused him of deceit.
"I stuck to the agreement," said Vettel, revitalised in Sochi after his first win in 13 months a week earlier in Singapore.
"I spoke with Charles before the race and it was all quite clear."
- Leclerc deserved better -
