Sunil Gavaskar has thrown his weight behind the selection of Karun Nair in India's new-look Test squad for the England series, praising the batter’s consistency and red-ball form. Speaking to India Today after the squad announcement, the legendary opener said Karun deserved his comeback, and pointed out that players like Jaydev Unadkat have shown how persistence can pay off in Indian cricket. "Even Jaydev played his first Test at a very young age, and then it took 13 years or so to play another Test. He persevered, he went on picking wickets in domestic cricket. Like Unadkat, Karun has kept on scoring big hundreds. That's why the selection committee had to bring him back. A man in form is one of your best bets. He is scoring runs, he also got the experience of County Championships," Gavaskar said. Calling it a "very good call" to bring Karun back, Gavaskar emphasised the value of form and domestic performances. Nair, who last played Test cricket in 2017, has recently been among the top scorers in the Ranji Trophy and has a triple hundred in his name from a previous Test series against England.

With competition intensifying, Gavaskar offered a clear message on how players must approach their chances. "It's tough, that's what cricket is all about. When you get opportunities, you have to make sure the place is yours. Even if you score a hundred, you should make sure that you don't go into your next innings thinking you scored a hundred in the previous knock. You have to get your eye in and get those runs again. You must not give anybody a chance to push you out of the team," he said.

"It's entirely up to you to ensure you cement that spot. You need to keep knocking on the doors and break the doors down." Reflecting on Sarfaraz’s absence, Gavaskar noted the lack of red-ball cricket after the Australia tour: "I think it's a tough call because after the tour of Australia, there was no red-ball cricket. Yes, there was the Ranji Trophy, but he was injured. So, he didn't play. There was no way he could show what his form was. You have to be undroppable. We have seen in the past, if a team loses a series, the guys who are 13th, 14th, 15th in the squad get dropped. You have to take your chances," he concluded. Sarfaraz has played six Tests for India so far, scoring 371 runs at an average of 37.10, with one hundred and three fifties.
