1. Marnus Labuschagne

There is no doubt that Marnus Labuschagne has given some decent performances in the middle order, but with the retirement of Steve Smith, a decision could be made to move up the order to Steve Smith’s position. Labuschagne has experience in anchoring the innings not only in ODIs but in Test cricket as well. The 30-year-old batter known for his elegant strokeplay and ability to play long innings could be the perfect replacement for the Aussie legend at number three.
Speaking of Labuschagne's ODI record, he has played a total of 63 ODI matches and has scored 1869 runs at an average of 35.94 and has scored 2 centuries and 12 half-centuries. Labuschagne could also be a captaincy prospect in the future.
