"This reflects dissatisfaction with the results and most likely a loss of patience on the part of the Renault group's management committee," Abiteboul, now Hyundai's World Rally team principal, said to France Info.
"Beyond impatience, there may also have been a bit of arrogance at the start of the season or overconfidence. When you don't confront reality, after a while you can tell yourself stories.
"It is not excluded that the story that we told ourselves internally was too flattering. But Alpine isn't that far off either.
"The previous management wanted to do a complete reset after my departure, which had dismissed about fifteen people. We underestimate him all the time in F1 as in other ultra-competitive sectors: getting someone from the competition takes time.
"When you lose 15 people and recruit… It takes two to three years before it takes effect. The reshuffle that Laurent Rossi wanted to do, we didn't even really see what he gave."
