Both have been relative failures in the first two matches but both have given glimpses of their sublime touch and assuredness. If the two are able to spend quality time in the middle, and Tillekratne Dilshan is able to convert his blazing start, Lankans have enough all-rounders to post a sizeable total on the board.
Sri Lanka are unlikely to make a lot of change to their playing XI although they could look at the all-round ability of Thisara Perera at the cost of Dhamika Prasad but it's unlikely they would pull out Sachithra Senanayeke since the off-spinner could find the bounce of Adelaide Oval to his liking.
It could also turn out to be a battle of wits between captains Jayawardene and Dhoni. The Sri Lankan skipper is more of a gambler, attacking all the time and never taking his foot off the pedal even when the rival batsmen are on the go. He choked Australia the other night and could very well do the same against India tomorrow.
Dhoni, on the other hand, prefers packing one side of the wicket with fielders and demanding a consistent line from his bowlers.
The Indian captain is more comfortable chasing a target than setting one and it wouldn't surprise many if he is seen chasing a target once again if situations favour his team.
In all the three matches so far, Indians have chased a total. In Melbourne, it cost them dear in a rain-curtailed match but in the next two games, it's been a happy ending.
It's fair to say that the batting is now shaping up nicely and could only get better from now on.
Ranganath Vinay Kumar has been the unsung hero of this Indian team. Bangalore medium pacer has accounted for six victims in three matches at 22.50 average and an economy rate of only 5 runs per over.
He has invariably given India the breakthrough and is now an integral part of the playing XI.
If the rotation policy is kept in place, it could be Virender Sehwag cooling his heels in tomorrow's game. Tendulkar is due to return and it could well be the day when the great man finally meets his long-pending milestone of 100th international century.
Wade traded football career in favour of cricketIt could be fitting too if Tendulkar reaches the coveted landmark in Sir Don Bradman's hometown.
Thus Tendulkar could be opening with Gambhir, the latter fresh from his exploits against Australia, on Sunday. The left-hander looked extremely assured during his 92 against Australia and could be looking for a repeat act tomorrow.
The middle-order too is beginning to bloom well. Virat Kohli, despite his relative failure, looks in sublime touch. Rohit Sharma and Suresh Raina, the two relative failures in the first two games, picked up their paces in the last match.
Dhoni too found his bearing and lived up to his reputation as a dangerous floater in the lower half.
The match is likely to be a high-scoring affair and it wouldn't surprise anyone if the skipper winning the toss, opts to field first and bank on batsmen to chase through any target which is set for them.
