Well assuming the Australian Test XI in Sri Lanka will be -
9.Warne/MacGill (tiny chance of both)
So who should come in at 6 to replace Waugh , there are 4 or 5 realistic contenders plus a few outsiders , if they wanted to play 5 bowlers then Shane Watson could be a remote chance.
Personally I'd want Lehmann there , he's a superb player on the slow wickets & has handled Murali well in the past , I really beleive he has a huge part to play if Australia is to finally triumph in Sri Lanka & India later in the year.
I also hope they have faith in Warne despite his lack of match practice , I dont think that MacGill is up to it (at least not as our sole frontline spinner) & although it may take Warne a while to get back into things Im sure he'll be able to repay the faith.
(Also he only need 29 to overtake Courtney Walsh , but Murali is catching up on him so if he dosent play in that series he may well be 3rd man to 500 )
