Williams driver Carlos Sainz called for an FIA investigation as he felt that the outcome of the Monaco Grand Prix was unjust. Lando Norris of McLaren took his first-ever victory at the iconic venue, but Sainz was more frustrated by those in the midfield he was battling with for the majority of the race.

Unusual tactics were deployed due to the new mandatory two-pit-stop rule, forcing each driver to stop at least twice. However, it brought out drivers slowing down on purpose, knowing that those behind them could not overtake on a tough Monaco track, effectively giving their team-mate an easier opportunity for a pit stop.

Sainz fumed at Racing Bulls for this strategy, pointing out how Liam Lawson deployed it to aid team-mate Isack Hadjar early in the race, an unconventional move that Williams themselves were forced to copy later. The Spanish driver felt that such racing was "manipulating the outcome a bit" and encouraged the governing body to get involved.

"[We were] driving four seconds off the pace at some stages of the race," Sainz said. "Ultimately, we were victims, first from Lawson that managed to lose 40 seconds to Isack, [it allowed] two pit stops that Isack would do in front of us to finish, to do his two pit stops and finish P5.

"As we were victims of that situation, we had to, in the end, do the same thing as Lawson did both times with Alex [Albon] and myself to make sure we bought the two cars to the points, something I definitely didn't enjoy doing, something definitely the sport should look into.

"Ultimately, yeah, you're driving two or three seconds off the pace that the car can do. You are ultimately manipulating the race and manipulating the outcome a bit.

"So we should find a way that this cannot be done in the future because of the feeling then every year, people are going to do it more and more, and it's becoming more of a trend the last few years.

"So in that sense, the two-stop, if anything, helped to maybe spice up around the pit windows, to have two pit stops, but it made us have to do the slow driving twice, which is not a very good look for the sport."

Racing Bulls were largely praised by the Sky Sports broadcast for their handling of the new rules, as Hadjar took sixth and Lawson came away in eighth place for their best result of the season.

Both Williams drivers were in the points at ninth (Albon) and 10th (Sainz) but team principal James Vowles felt compelled to his Mercedes counterpart Toto Wolff for the tactic, which enraged George Russell as he was kept behind the pair.

Wolff read out a text message he received from Vowles while in a Sky interview, which stated: "'I'm sorry. We had no choice given what happened ahead.'”

The Mercedes chief did accept the apology, but Sainz was still aggrieved at what he believed to be unfair driving, urging the FIA to take a close look at the incidents.
