Sainz fought with Esteban Ocon for the final podium when he was called to a pit stop as Ferrari tried to undercut to gain track position over the Alpine driver.
Although the decision meant Sainz was able to overtake Lewis HamiltonMercedes at this stage of the race, the Spaniard was angry that he was still stuck behind Ocon.
“That’s exactly what I was talking about!” Sainz raged.
His race engineer Riccardo Adami replied: “The goal was to cover Hamilton.”
“I don’t care Hamilton, I was fast!” Sainz jumped back.
For the second time in many years, Ferrari’s Monaco strategy is being called into question.
Last year, Ferrari’s disastrous strategy resulted in pole position Charles Leclerc he lost his chance to win his home race as he dropped to fourth place.
Sainz wasn’t the only driver to be furious with his team during Sunday’s rainy race.
The AlphaTauri were left at the end of receiving Tsunoda’s usually unfiltered feedback.
When Tsunoda was having problems with his brakes, his race engineer Mattia Spini gave the following advice: “Offset 5, increase it when braking. You can do it.”
“I know, but that brake sucks!” Tsunoda replied before adding “Are you trying to break me up or what?”
Explaining his difficult race, Tsunoda said: “The brake problem I had all weekend got worse in the rain and it was difficult to control and manage the situation. From that moment until the end of the race I felt like a passenger.
“Of course I’m frustrated and so is the team because points were possible today. It’s hard to accept, there are still things to improve, but you can definitely take the positives from this weekend.
Now we will reset and focus on Barcelona.
