Toto Wolff is not used to losing but his Mercedes' drivers weren't even on the podium in Monaco
Lewis Hamilton had the worse weekend of the two drivers, qualifying in 14th and finishing seventh in the race after problems getting his tyres up to optimum operating temperature.
Valtteri Bottas was slightly more successful although he failed to convert 3rd place on the grid into anything better than 4th, having been jumped in the pit-stop phase by Red Bull’s Daniel Ricciardo.
And Mercedes team boss Wolff told his team in an email that he had woken up on Monday morning at 4am feeling ’s**t’ because they had not won a Grand Prix.
The winners of the last three F1 World Constructors’ Championships find themselves 17 points adrift of Ferrari after six races ahead of this weekend’s Canadian Grand Prix in Montreal.

They also trail in the Drivers’ Championship with Sebastian Vettel 15 points ahead of Hamilton and Bottas another 29 points back.
But Wolff insists the team will not favour either driver in its strategic planning, despite Hamilton appearing to be better placed to challenge for top honours.
“We have two excellent drivers and we will hold true to our philosophy of letting them race each other to drive the team forward – even if sometimes it can be difficult because you can’t always have the one who is ahead in the championship winning,” Wolff said.
