"Obviously the safety blanket for him would be moving back to No. 4, but I would love to see him continue to take on the opening spot because he's got the skill to be able to do it," Watson said at the sidelines of the launch of the International Masters League in Mumbai on Tuesday.

"Cameron Green came in and batted at No. 4 and did a brilliant job," Watson said. "His hundred that he got in New Zealand was something very special and he's the perfect No. 4 candidate now with the future, moving forward."

Smith's four-Test stint as opener so far has yielded 171 runs - over half of which came in one innings against West Indies - at an average of 28.50, but Watson thinks it's not a problem caused by his batting position.

"I believe the reason why he didn't do so well over the previous couple of Test matches is just [that] he was a little bit off with his technique," Watson said. "You see [saw] him getting out a couple of ways which I've never really seen him get out before.

"I know he would've had time just to go away, make some little technical adjustments, and if he opens and he makes those little adjustments, he can be incredibly successful as an opening batter knowing the incredible skill that he's got."

"I'm a traditionalist at heart. Growing up, the Gabba was always the first Test match and that's the Test match I used to go to," the former Australia allrounder said before highlighting the challenge Gabba poses to visiting sides.

"The Gabba is a more challenging place to play for the foreign teams because there's bounce, there's seam, there's swing, and it's hot and humid. So it just provides a few more challenges, whereas Perth, for example, it's not humid, the ball doesn't swing as much, doesn't necessarily seam as much as well.

"I always just love the Gabba as being the place for the touring team to be able to come in and have to try and just take on the Australian conditions at their most challenging."
