Gareth Bale is poised to become the second Welshman to the 100-cap milestone in their World Cup qualifier against Belarus.
Bale has been out for two months after a hamstring tear but is set to lead Wales in their penultimate qualifier in Cardiff on Saturday.
"To get 100 caps personally would be an incredible achievement," said Bale, who will follow 106-cap Chris Gunter to the landmark.
"You never think about when you're first starting out, but to be on the cusp of it is nice for me and my family and hopefully we can enjoy it.
"But the most important thing is the game and not the occasion. As soon as that whistle goes I won't be thinking of anything else than getting the three points."
Bale has not played since Wales' goalless draw against Estonia on 8 September.
He said: "I'm obviously not in peak condition like I was before my injury. I've worked probably harder than ever to try and get back.
"I'm not sure if going to play the full game. I have to be wary as I haven't played for two months, but I'll give 100% and that's what I always ask of myself."
Wales are already guaranteed a World Cup play-off spot through their Nations League results, but four points from closing qualifiers with Belarus and Belgium could give them a home semi-final tie in March.
