After watching the leg spinners demolish his all-star batting line-up in the ICC Super Series Test at the Sydney Cricket Ground, the South Africa skipper is highly impressed with MacGill and Warne's combination.
Despite the threat of the pair doing the same to his Proteas during a three-Test tour in December, Smith thinks Australia should keep MacGill in the team to meet West Indies in Brisbane next month.
"It looked like a good unit. It looked like they had options. The wicket is going to play a big part in the selection for them but this side as they have it now is a good, balanced side," Smith said before leaving Sydney last night.
"I think Stuart and Warnie work well together. Warnie has the control and the guile while MacGill has a very aggressive style of play.
"He is hungry for wickets, and the way he played it is a good partnership (for Australia)." Smith's comments came as Terry Jenner, Warne's long-time mentor, also backed calls to persist with MacGill.
