Sudharsan has been included in India's squad for the upcoming tour of England.
"It obviously feels great. Feels very special to be honest, and surreal also. Any cricketer, any young cricketer who starts playing cricket, wants to play Test cricket, wants to play for the country," Sudharsan said, as quoted from ESPNcricinfo.
"The ultimate goal is always to play Test cricket. So really happy for that," he added.
There was a lot of anticipation surrounding the squad as the veteran duo of Virat Kohli and Rohit Sharma recently announced their retirement from the traditional format.
During the five-Test series against England, the onus will be on KL Rahul, Yashasvi Jaiswal, Shubman Gill and Rishabh Pant to provide much-needed experience in the batting department. Sudharsan is expected to be part of India's new-look top four. Karun Nair has also returned to the Test fold after seven years on the back of his stunning exploits in domestic first-class cricket,
While Sudharsan opens the batting for Tamil Nadu in the Ranji Trophy, he has expressed his readiness to bat in any position for the national team.
"Sir, I think playing for the country itself is a very big privilege for a cricketer. So I don't think I am in a position to choose where I want to play," the southpaw stated.
"Wherever the coaches tell me to play, I think I will be mentally and obviously skillfully, you know, try and be ready for the opportunity," he added.
"I have a lot of likings. I think I will have to be ready for whichever (position) the team gives me. I will be ready for that," he noted.
Gill has been handed the Test captaincy, with Pant being named his deputy as India embark on a new World Test Championship cycle with the England tour.
On the prospect of making his Test debut under Shubman, his captain at Gujarat Titans, Sudharsan said: "I mean, Shubhi (Shubman Gill) is, over the years, I have been a part of his growth as well."
"I have seen him for the last four years. Such a talented batsman, such a skillful batsman, anybody can see," he added.
"So I feel he will definitely do laurels and great things for the country and I am grateful and I am very happy to play under him in my first Test series," he noted.
Ahead of the marquee series, both Sudharsan and Gill will join the India A squad for the second four-day match against the England Lions, scheduled to start on June 6 in Northampton.
"I always feel finish the first story, then go to the next one because now the IPL is also most important when we are in IPL (Indian Premier League)," Sai said.
"So I think it is also most important of finishing this and then obviously we will have time to prepare. So I will use that bracket of days so that we will be ready for the Test series," he added.
For now, however, Sai Sudharsan remains focused on the business end of IPL 2025. He also acknowledged the unique challenge of switching from the high-paced T20 format to the demands of Test cricket.
"Transitioning from white ball to red ball takes a bit of time," he said. "I think I focus a lot more on my basics. I focus a lot more on my patience even outside the field."
"The more patient you are, the more it reflects inside the field. So, Test cricket is all about patience and longevity. So I feel the more I focus on that, the more I be aware of it, I think it will be a great experience," he remarked.
