But if Tendulkar is found unfit, which is highly unlikely, Tamil Nadu opener Murali Vijay is expected to take his place in the side.
The rest of the batting line-up is, however, expected to have familiar and established stars.
The opening slots will be filled by Virender Sehwag, and Gautam Gambhir and it will be interesting to see whether reserve opener Vijay stands as both the first-choice batsmen have been given precautionary rest to heal their niggles.
The middle-order will most certainly feature the never to be underestimated Yuvraj Singh, who returned to form on Saturday with a well-made 53, and the young trio of Suresh Raina, Virat Kohli and Rohit Sharma.
The ongoing ODI series in South Africa was supposed to give a chance to the probables to prove their worth but skipper Mahendra Singh Dhoni has already poured cold water on suggestions that the performance there would make much of a difference to the World Cup squad.
"Not really, as not just one performance will matter. Guys who have worked hard for the last year-and-a-half they may get a chance.''
"I think for the World Cup, fight is on for just one or two position as rest of the players will choose themselves. Basically, it is up to the selectors," Dhoni has said.
Munaf propels India to thrilling one-run victory against South AfricaOn the bowling front, India does not have much of a pool to choose from. The inspirational Zaheer Khan will lead the attack and in all probability his pacer partners would be chosen from the quartet of Ashish Nehra, S Sreesanth, Munaf Patel and Ishant Sharma.
Of these, Sreesanth, Ishant and Munaf have come up with reasonably good performances in the series against South Africa.
Harbhajan Singh will spearhead the slow bowling department but it is hard to guess on who among Amit Mishra, Piyush Chawla and Pragyan Ojha would get the selectors' nod in the pruned squad.
The all-rounder's slot has always been a selection headache but despite the absence of options, it would be quite a gamble to pick an inconsistent Ravindra Jadeja.
It remains to be seen whether the selectors will opt to have a reserve wicket-keeper in the squad in case of an injury to skipper-stumper Dhoni. The toss up then will be between Parthiv Patel and Dinesh Karthik even though Wriddhimaan Saha has also been tested in the past one year.
