Rahul, who returned after an injury lay-off, proved his fitness and form after scoring a century for Karnataka against Rajasthan in Ranji Trophy today (November 15).
The 24-year-old opener has made his contention stronger after hitting a magnifienct century against Rajasthan in the domestic circuit.
Rahul scored 106 runs of just 131 deliveries, an innings studded with 13 fours and four sixes and at a devastating strike rate of 81.
He was ruled out of the Indian Test squad after sustaining a hamstring injury during first Test match against New Zealand at Kanpur.
Rahul's inclusion into the squad poses a big threat to the position of veteran batsman Gautam Gambhir.
Gambhir made a comeback into the national side after a gap of two years, as a replacement to Rahul. But he failed perform in the opening Test against England.
The southpaw scored 29 in the first innings while departed in the 2nd innings without even opening his account in the first Test at Rajkot. Gambhir's dismissal in the both the innings at Rajkot was critically analysed and questions were raised on the 34-year-old batsman's technique.
Gambhir failed to impress even in his comeback Test at Indore, where he scored 29 and 50 and spent most of the time into the dressing room.
Since India failed to get a good start against England in the 1st Test, there is a possibility that team management would once again rely over Rahul, who has been in tremendous form, this year.
Rahul has been only the second best batsman for India after star batsman Virat Kohli in the year 2016.
Even the timing of Rahul's induction into the side possibly hints towards the fact that team management wants its opening woes sorted out.
