France prop Nicolas Mas is soaking up the experience of preparing for his third and final Rugby World Cup.
The veteran tighthead is still one of the most highly respected tighthead props around in the game today.
Mas has played in two previous World Cups in 2007 and 2011 but was not selected in the first three matches of this year's Six Nations before returning against Italy and England, as France looked at other options.
The 35-year-old however holds no grudges over his omission.
"I'm not out for revenge because it was the choice of coaches. It's up to them and the France shirt belongs to no one," Mas told Rugbyrama.
"With the emergence of very good players like Uini (Atonio) and Rabah (Slimani), they are the future and that is important for France.
"I want to take full advantage of these moments because it's a privilege. In normal life, we will never have these experiences again. I want to get my teeth stuck into this preparation. I won't give up."
Despite that enthusiasm, Mas admits that getting ready for the Rugby World Cup is not so much a case of something he enjoys as a necessity, as the squad binds together.
"I don't know if 'like' is the word… this is something that we must do in the sense that you really need to prepare well for the World Cup," he explained.
"In normal seasons, sometimes we only have fifteen days to prepare for the championship, while now we have had a big block of physical preparation before us. It's really good to be able to develop all that to be effective for those who have the opportunity to go to the World Cup.
"In a squad, cohesion is very important because not everything will be rosy and it will be hard. It's in these moments that we find ourselves, and we see if we are a real team or not."
