Former England captain Michael Vaughan has revealed what Marnus Labuschagne must change in his game to rediscover the form that made him the world’s No.1 batter.

As India trained at Perth Stadium for the first time on Tuesday ahead of Friday’s Test, the Aussie No.3, who is averaging little more than 30 in Tests since the start of 2023, was thinking about the flaw that has crept into his armoury over the last two summers.

After establishing himself as one of the world’s leading Test batters by frustrating bowlers with his ability to leave deliveries outside the off-stump, he has lately gotten into a habit of flirting with wider deliveries and nicking off.

“For me, probably getting away from the process of what makes me a good player [has been a problem] and [it’s about] just making sure I stay consistent to that process and really trusting the system,” Labuschagne said in Perth on Tuesday.

“My best preparation is always thinking at the other end and thinking about how they’re going to attack me, and me being able to develop and change my game to what the best method is to attack them.

“It’s going to be important for all of us – the way we play when we’re at our best, we’re playing the long game, we understand that you need to be getting them back for their second and third spells, putting them under pressure and letting them come to us, and us putting pressure back on them through overs in the field and time in the game, especially over a five-Test series.

“As you get into the third, fourth, [and] fifth Tests, if they’re trying to play the same team and those bowlers are rolling into 150 to 200 overs by the third Test, it’s going to make a big difference in the series.”

Labuschagne looked to remedy the situation and spent time with his batting coach during the year as he attempted to rediscover the process that led to success. Vaughan backed Labuschagne to play himself back into form.

“My message to Marnus would be to get back into your box and play the way you used to play,” Vaughan told The Sydney Morning Herald.

“Play with patience, great discipline, and expect they are going to bowl fourth stump, at length, just on that channel. That’s where India are going to challenge him.

“If he can leave those balls, they are going to have to come a bit fuller, and then he will get a drive away, or they will have to go a bit straighter. I think in recent times he has almost been trying to hit the ball too much.”
