I don't think Murali's bowling would make a huge difference in 20/20 . That's just my personal opinion.
Murali is needed for SL tour of Australia which is IMHO the No.1 priority ATM.And everything else is insignificant. Thats my personal opinion.
In eight games in all Twenty20 cricket, he has 17 wickets - over two a game - at an average of 9.17 and an economy rate of 5.37. They are almost unbelievably good stats. Murali would probably have been the first choice bowler for any side. Players like Lokuarachchi who can offer a bit with the bat won't have as much impact as you expect - Twenty20 games are largely won by the top 4, top 6 at a push.
Murali can now concentrate on the real stuff in Australia. Blessing in disguise.
His loss is an absolutely huge blow to Sri Lanka’s chances.
I'd go further and say that if you were picking a world Twenty20 side from scratch, Murali would be my first pick.
I am only hoping he is not going to use this to take an extended period off Cricket, under the excuse of "injury" to avoid going to Australia.
The latest is Murali is definitely out of 20/20.
If Sri Lanka make it to the last 4 -wouldn't be surprised if Murali's injury makes a miraculous recovery and he gets flown in to SA .:)
