Komatsu admitted that the team had called Magnussen into the pits at the wrong time, losing the Dane two places in the process.
Like in Saudi Arabia, Haas split the strategies of the two drivers, with Nico Hulkenberg running a long opening stint on the hard tyre before pitting for mediums under the VSC.
With fresher tyres, Hulkenberg came up behind Magnussen who, despite his obvious frustration after the earlier pit call, duly moved over and let his team-mate use his pace.
The pair eventually finished ninth and 10th, with both men gaining a spot after George Russell’s late accident.
It was the second race in a row that Magnussen has helped Hulkenberg, having held up a group of cars in Jeddah.
“On the first round of pit stops for Kevin, we lost two positions,” said Komatsu.
“That shouldn't have happened. But other than that, everything else was amazing.
“Pitstops were amazing, and then the drivers working together again during the second stint - Kev was on the hard tyre, Nico was on the medium tyre, because of the VSC.
“Again, Nico had a better pace. But Kevin's strategy was already compromised, not because of his fault – the team's fault.
“So Kevin had every reason to be pissed off, but then no: when we asked to swap, he's done it straight away. So he knows how important these opportunities are. So, just right.”
Asked about keeping the pair together for 2025, Komatsu said: “I haven't thought about that. I know that driver market is very open. I need to think about that pretty soon.
“But at the moment, until we do the first four or five races, I'm just fully focused on working together as a team.
“Honestly, Kevin today, hats off to him. It's just unbelievable team play. Really amazing.”
Komatsu explained that the team reacted to Alex Albon stopping, when it should have kept Magnussen out.
“Albon pitted,” he said. “He's already undercut us. So we shouldn't have then pitted on the following lap.
“But we did. So we let Albon undercut us - for no reason.
“Then, if you look at [Esteban] Ocon, he went longer on the first stint, and basically overcut us. So we lost the two positions. That just is not right.
“We cannot be keep making those mistakes when everything in the midfield is so tight.”
Komatsu admitted that it was frustrating that both drivers lost out to the RB of Yuki Tsunoda, with Hulkenberg having been 'best of the rest' in Jeddah.
“Tsunoda had a better pace than us,” he said.
“But again, if we did our first round of pit stops right, and then with the pace we had on the second stint, I think we could have fought with him much, much closer.
“But just we need to put ourselves in that position first. But you know, full credit to Tsunoda, I think his pace was good today.
“But I feel if we've done the perfect job with Kevin, Kevin had the chance to fight with him until the end. That's what we should be doing.”
