Sergio Perez (Accident, Lap 1): 3/10
Following on from his disastrous weekend in Imola, Sergio Perez really needed a restorative weekend in Monaco - a track he won at just two years ago, let's not forget, so this should have been a top opportunity for him to remind people how good he is. Instead it all went terribly wrong for the Mexican. Red Bull was struggling from the start and when it came to qualifying, "Today was a complete disaster - we didn't get into the rhythm and we didn't have the pace." Missing the first cut is unforgivable and there was no way back from there even before he was spun out by Kevin Magnussen and his car comprehensively dismantled in the ensuing accident. No wonder Perez said he was feeling shaky afterwards - much like his hold on the race seat for 2025.
Esteban Ocon (Accident, Lap 1): 4/10
Judging from his practice performances, it looked as though Esteban Ocon was going to struggle to make the first cut in qualifying. But in the end he made it through to the second round and only missed a Q3 appearance by less than a tenth to Alex Albon. He ended up starting the race right behind his Alpine team mate Pierre Gasly, and that's when it all unravelled: despite a rumoured pre-race agreement for the pair not to fight each other at the start, Ocon couldn't resist the chance to make a dive on Gasly to run him out of room at Portier. It resulted in Ocon's car being jolted into the air inflicting race-ending damage. It was additionally censured by the stewards with a grid penalty for Canada, and Alpine boss Bruno Famin looked furious at the breach of good faith. To be this needlessly aggressive toward a team mate compromises the ongoing viability of squad dynamics.
