Carlos Sainz left the Monaco GP weekend a frustrated figure, unhappy with the FIA's lack of consistency in applying penalties for ignoring blue flags.
Sainz himself received a reprimand and a fine for impeding Lance Stroll in Free Practice, but the Spaniard feels other drivers were not penalised for similar or even more severe transgressions during the race and throughout the weekend.
Sainz told motorsport.com:
"I cannot count the times I got impeded in Monaco this weekend, both being dangerous and not dangerous.
What I don't understand is why we got fined €25,000. Other cases are not investigated, and other people are not fined for exactly the same thing."
Both Ferrari's will feel that backmarkers compromised their race. Alex Albon spent an entire lap ignoring blue flags whilst running in front of Charles Leclerc, who could only pass after the Williams driver made a mistake and went wide into turn 1.
Ultimately, Sainz and Ferrari can feel justified in their frustration with stewarding decisions made by the FIA, but this will do little to remedy their poor form in the last few races. The Italian squad must cut out unforced errors if they are to sustain a championship fight against Red Bull.
