O'Gara, who gained valuable experience in New Zealand with the Crusaders and with Racing 92 in France, has led La Rochelle to back-to-back Champions Cup titles, both achieved against Leinster.
There is a belief that O'Gara will go on to achieve great things elsewhere, perhaps with an international side like Ireland or England, or even with a club team such as Munster one day.
Speaking of Munster, the Champions Cup draw has paired La Rochelle with Munster in the next round of the competition.
Munster, whose motto is "Stand Up and Fight," will now bring the fight to France. Known for their gritty determination, many Munster players thrive in tough encounters, and O'Gara himself epitomizes that fighting spirit.
Dusautoir praised the Cork native for bringing this same resilience to La Rochelle and explained further why he has been so successful in France.

"He speaks good French and expresses himself well. What he did in La Rochelle was to change the culture of the city and the team," said the former French international in an interview with Genting Casino.
"He has done it the right way. Remember, he started at Racing 92 about 10 years ago, so he already understood French culture. He also had the experience of New Zealand with the Crusaders. He never tried to move too quickly.
"When he came to La Rochelle, he brought the Munster culture, where you represent your city, your family, and the fans. You’re not just playing for yourself; you’re playing for the jersey. This is really important, and you can sense it when he speaks.
"He’s a good coach because he’s never satisfied. He always looks for ways to improve and does things the right way. He went to Paris to learn. He spent time with the Crusaders. He built his experience as a coach before stepping into the number-one role, which is crucial."
Dusautoir also highlighted how O'Gara’s time as an assistant coach at Racing 92 was invaluable for his development, helping him forge closer connections with players.
"It's important. If you compare Stuart Lancaster with O’Gara, those years as an assistant coach at Racing helped him understand the role better. As an assistant coach, you're closer to the players, so you can communicate differently and learn from them.
"It really helped him grasp the way we think because, I have to admit, we French are different! We are very emotional. We don’t experience rugby the same way as the English, for example. England is more pragmatic."
