Shaw dazzled with a 69-ball 66 in his very first innings in Australia, having made his Test debut only last month against the Windies at home.
Although his opening partner KL Rahul couldn't match Shaw's performance and was dismissed for three, and Murali Vijay, the third opener in the squad, didn't get a bat, Bangar feels India are still undecided on who the openers for the first Test will be.
"We are not even thinking about personal performances. Just one aim, that is to win a series in Australia."

"I would say there are still some spots to be taken," Bangar told reporters at the end of day two of the four-day game as CA XI finished on 24/0 in reply to India's 358 in the first innings. "We will also keep a close eye on how second innings goes.
"We might give some other batsmen a hit, push them up the order a bit and see how they go. So there are certain spots there to be taken for the first Test. We are looking at the opening slot as well as the No.6 slot. Those are the positions we have not decided yet."
Shaw's wasn't the only big contribution in India's first-innings total as all of India's front-line batsmen, Cheteshwar Pujara (54), Ajinkya Rahane (56), Hanuma Vihari (53) and captain Virat Kohli (64), hit half-centuries.
With Rohit Sharma too chipping in with a 40, it was a satisfying day for the visitors. "[It was a] pretty useful time in the middle and it was important that we switch to this format of the cricket because a lot of guys have been coming from the T20 format," Bangar said.
"And the Test guys coming in, except for Pujara most of them had first-class game in New Zealand. Pretty happy that all of them got to spend some time in the middle and get some runs under their belt."

And while the CA XI side is bereft of top international cricketers, many of whom could be playing the Sheffield Shield at the same time as this game, Bangar said he had no qualms with the quality of the side Indians were up against and stressed the importance of getting accustomed to foreign conditions.
"Guys went out there with an intent to get accustomed to the bounce for those playing there first game in Australia," Bangar said. "No matter how different the conditions could be in Adelaide because this is not a fast paced pitch as you would expect there or in Perth, we were out here to make the most of whatever we got.

"From that perspective, Virat [was] switching format from T20 to a four-day format. Then Pujara, who missed a game in New Zealand, [was] straightaway coming back and settled into a nice groove. Ajinkya [was] spending a lot of time – he hit just one boundary but was making sure that he got to play a number of balls there.
"Hanuma Vihari, again, playing with a lot of confidence and clarity. Rohit coming back, again getting a knock out there, spending some time – [It was] a satisfying effort from our side."
The four-day match, which is India's only practice game ahead of the Tests ends on 1 December, after which the teams will lock horns in the first of four Tests at the Adelaide Oval from 6 December.
